Kirchhoff’s Voltage Law
According to Kirchhoff’s Voltage Law,
The voltage around a loop equals to the sum of every voltage drop in the same loop for any closed network and also equals to zero.
Put differently, the algebraic sum of every voltage in the loop has to be equal to zero and this property of Kirchhoff’s law is called conservation of energy.
When you begin at any point of the loop and continue in the same direction, note the voltage drops in all the directions either negative or positive and return to the same point. It is essential to maintain the direction either counterclockwise or clockwise; else the final voltage value will not be equal to zero. The voltage law can also be applied in analyzing circuits in series.

Kirchhoff’s Current Law
According to Kirchhoff’s Current Law,
The total current entering a junction or a node is equal to the charge leaving the node as no charge is lost.
Put differently, the algebraic sum of every current entering and leaving the node has to be null. This property of Kirchhoff law is commonly called Conservation of charge wherein, I(exit) + I(enter) = 0.
In the above figure, the currents I1, I2 and I3 entering the node is considered positive, likewise, the currents I4 and I5 exiting the nodes is considered negative in values. This can be expressed in the form of an equation:
I1 + I2 + I3 – I4 – I5 = 0
The term Node refers to a junction or a connection of two or more current-carrying routes like cables and other components.
Kirchhoff’s current law can also be applied to analyze parallel circuits.

Wheatstone bridge
Wheatstone bridge, also known as the resistance bridge, calculates the unknown resistance by balancing two legs of the bridge circuit. One leg includes the component of unknown resistance.
The Wheatstone Bridge Circuit comprises two known resistors, one unknown resistor and one variable resistor connected in the form of a bridge. This bridge is very reliable as it gives accurate measurements.

The Differential Amplifier
The differential amplifier amplifies the voltage difference present on its inverting and non-inverting inputs
differential amplifiers amplify the difference between two voltages making this type of operational amplifier circuit a Subtractor unlike a summing amplifier which adds or sums together the input voltages. This type of operational amplifier circuit is commonly known as a Differential Amplifier configuration

Cathode Ray Tube
CRT
Cathode ray tube display technology is mostly used in televisions and computer screens that work on the movement of an electron beam back and forth on the back of the screen. This tube is an elongated vacuum tube in which the flattened surface has external components as an electron gun, electron beam, and a phosphorescent screen

Decibels
Unit is Bel, but because this is large, deci-Bels (1/10th Bel) are used), Symbol is dB.
Decibels are used in audio because they are a logarithmic measure of voltage, current or power, and correspond well to the response of the ear.
A 3dB change is half or double the power (0.707 or 1.414 times voltage or current respectively).

What is wireless charging?
👉Wireless charging is a technology that charges devices without using connectors or metal contacts.
👉This is also referred to as non-contact charging, non-contact power transmission, and wireless power supply.
👉Wireless charging technology is attracting increased attention by eliminating the need for power cords when charging.
👉 This is expected to increase connector safety and resistance to dust and water while enabling multiple devices to be charged using a single charger.

What is a laser diode?
👉The LASER in Laser Diode is an acronym for 'Light Amplification by Stimulated Emission of Radiation'. It is also referred to as a semiconductor laser and generally abbreviated as LD.
👉Its main feature is high coherency, making it possible to emit light with the same phase and wavelength.
👉Laser oscillation is achieved by amplifying light generated through current injection between two mirrors. Simply put, a laser diode is an LED that amplifies and emits light using reflectors.

Designed to accurately produce the required output waveform with the addition of just a few extra timing components.
One such device that has been around since the early days of IC’s and has itself become something of an industry “standard” is the 555 Timer Oscillator which is more commonly called the “555 Timer”.
The basic 555 timer gets its name from the fact that there are three internally connected 5kΩ resistors which it uses to generate the two comparators reference voltages. The 555 timer IC is a very cheap, popular and useful precision timing device which can act as either a simple timer to generate single pulses or long time delays, or as a relaxation oscillator producing a string of stabilised waveforms of varying duty cycles from 50 to 100%.

What is a Schmitt Trigger?
A Schmitt trigger is a comparator (not exclusively) circuit that makes use of positive feedback (small changes in the input lead to large changes in the output in the same phase) to implement hysteresis (a fancy word for delayed action) and is used to remove noise from an analog signal while converting it to a digital one.
It was invented way back in 1937 by Otto H. Schmitt (whose legacy is somewhat understated) who called it a ‘thermionic trigger’.

Non-Inverting Op-Amp
In this configuration of Op-amp the input signal is directly fed to the non inverting terminal resulting in a positive gain and output voltage in phase with input as compared to inverting Op-amp where the gain is negative and output voltage is out of phase with input , and to stabalize the circuit a negative feedback is applied through a resistor(Rf) and the inverting terminal is grounded witha input resistor(R2).
This inverting Op-Amp like layout the at inverting terminal creates a virtual ground at the summing point make the Rf and R2 a potential divider accross inverting terminal, Hence determines the gain of the circuit.
