12 Supervision Report Forms are provided separately, on which you are required to: (a) supply detailed information about the equipment where necessary: (b) report on any particular difficulties experienced by any candidate, especially if the Examiner would be unable to discover these from the written answers; (c) report on any help given to any candidate under the regulations explained in 10; (d) report on any damage to equipment (see 8). 13 The candidates should be requested not to write out any detailed description of their computer work, but you or the person responsible are requested to give on the Report Form a brief description of the equipment supplied, mentioning any points which are likely to be of importance to the Examiner in marking the answers. 14 The Report Form should be signed by the Supervisor and by the person responsible for preparing the equipment.

*WAEC 2025 COMPUTER PRACTICAL SPECIMEN* 1 Great care should be taken to ensure that the information given below does not reach the candidates either directly or indirectly before the examination. (a) The timetable allows for the examination to be taken in two sets. Where a school is presenting candidates for the second set, the supervisor must ensure that the work from the first set is permanently deleted from the hard drive including the recycle bin. (b) Additional 5 minutes should be given to candidates at the end of the examination to print out their finished/unfinished solutions. (c) Invigilators should pick up candidates' hard copies from the printers and handover to the candidates to avoid overcrowding around the printer. (d) Candidates are to submit their printouts to the supervisor themselves. (e) The candidate's printout should be signed by the supervisor. (f) Schools should ensure that no candidate brings in any storage media (e.g. flash drive, compact disk, etc) into the examination hall. Turn over 2 The number of computers provided for the examination should be at least half the number of candidates who entered for the examination. For instance: a) a school presenting 20 candidates must have at least 10 computers. b) a school presenting 50 candidates must have at least 25 computers. 3 The computers should be connected to a local area network. 4 One high performance printer should be connected to at most 10 computers. (i.e. ratio of printer to computers is 1:10). 5 The Operating System for the computers should be Windows 7 or higher version. 6 The following application packages should be installed on each computer: a) MS Word 2007 or higher; b) MS Excel 2007 or higher; c) MS Access 2007 or higher; d) MS PowerPoint 2007 or higher. e) CorelDraw. 7 Schools are encouraged to provide additional PCs on standby in case of equipment failure. 8 If a candidate damages any of the equipment, the matter should be reported and a note made on the Report form. 9 The purpose of the practical computer studies test is to find out whether candidates can solve simple problems of the type described. The Examiner is aware that a candidate may find it very hard to make rapid progress when using equipment to which he/she is unaccustomed, or when under examination conditions. If the Examiner is unable to discover from the written answers whether a candidate has been prevented from demonstrating his/her competence by this, he/she should refer to any notes made on the Report form. For this reason, you should be ready to provide alternative computers should one fail during the test, and you should also allow the Computer Studies teacher in your school or another person to attend to minor difficulties. 10 The following regulations must be strictly adhered to: (a) The test may be administered to candidates on a whole. (b) A candidate who is unable to proceed and requests assistance must come up to you and state his/her difficulty. The candidate should be told that the Examiner will be informed of any assistance given to him/her. (c) A note must be made, on the Report Form, of any assistance given to any candidate, with the name and index number of the candidate. 11 It is suggested that the following announcement be made to the candidates: "The Examiner does not want you to waste your time through inability to proceed with the practicals. Therefore, any candidate who is unable to proceed and requests assistance should wait for 15 minutes or so, then come to me and ask for help. I shall report to the Examiner any help given in this way, and some allowance may be made for the help received. You may ask me for any additional equipment which you think would improve the accuracy of your work and you should state on your script how you used such equipment.

(1a) (i) Lenz's Law: Lenz's Law states that the direction of an induced current is such that it opposes the change in magnetic flux that produced it. This is a consequence of the conservation of energy and is represented mathematically by the negative sign in Faraday's Law: E = -dΦ/dt (ii) (a) Controllability: The magnetic field strength of an electromagnet can be easily adjusted by changing the current, whereas a permanent magnet has a fixed magnetic field. (b) Temporary Magnetism: Electromagnets can be turned on and off, making them more versatile for applications like electric motors, relays, and magnetic cranes. (1b) Given: Number of turns, N = 10 Current, I = 3 A Length of magnetic path, l = 25cm = 0.25 m The magnetic field intensity (H) is given by: H = (N × I) / l Substituting the values: H = (10 × 3) / 0.25 = 30 / 0.25 = 120 A/m Magnetic field intensity, H = 120 A/m

*WAEC BASIC ELECTRICITY* *NUMBER SIX* (6a) Lightning Arrester: (i) Diverts lightning surges to earth. (ii) Protects transformers from high voltage. (iii) Prevents damage to substation equipment. (iv) Limits transient overvoltages. (v) Ensures safety during lightning storms. (6b) Circuit Breaker: (i) Interrupts current during faults. (ii) Operates automatically or manually. (iii) Protects equipment from overload. (iv) Isolates faulted sections. (v) Ensures system stability. (6c) Isolator: (i) Disconnects parts of the system. (ii) Used during maintenance. (iii) Operates only under no load. (iv) Provides visible isolation. (v) Enhances safety for workers.

ANSWERS 1. (a) (i) Lenz’s Law: Lenz's Law states that the direction of the induced current in a conductor is such that it opposes the change in magnetic flux that produced it. (ii) Two advantages of electromagnets over permanent magnets: 1. Electromagnets can be turned on or off as needed. 2. Their magnetic strength can be varied by adjusting the electric current. (b) Given: Number of turns, N = 10 Current, I = 3 A Length of magnetic circuit, l = 25 cm = 0.25 m Magnetic field intensity -- 2. (a) Impedance of an a.c. circuit: Impedance is the total opposition that a circuit offers to alternating current. It includes both resistance and reactance, and is measured in ohms (Ω). (b) Sketch a sinusoidal waveform indicating: (i) Amplitude — the peak value above or below zero. (ii) Cycle — one complete wave from 0 to +peak to 0 to -peak and back to 0. (c) Given: RMS voltage = 220 V (i) Maximum voltage (Peak value): (ii) Average value (for a sinusoidal waveform): --- 3. (a) Total power: 10 lamps × 60 W = 600 W 5 fans × 74 W = 370 W 5 ACs × 746 W = 3730 W 1 cooker = 2500 W Total = 600 + 370 + 3730 + 2500 = 7200 W (b) Energy consumed in 5 hours: Energy = Power × Time = 7200 W × 5 h = 36,000 Wh = 36 kWh (c) Using a 1.5 mm² cable for the electric cooker (2500 W): This cable size is too small and may overheat, posing a fire hazard. It can cause voltage drops and reduce the efficiency of the cooker. 4. (a) Sketch of a shunt motor: Armature and field windings connected in parallel across the power supply.
