✨Digital multimeters (DMMs) are versatile electronic measurement tools used to measure various electrical parameters such as voltage, current, resistance, and continuity.
They typically have a range of symbols on their display to represent different measurement functions and settings.
Here are some common symbols you may encounter on a digital multimeter:
1⃣Voltage (V): This symbol represents the measurement function for measuring voltage. It is usually denoted by a capital "V" or a V with a straight line above it.
@theelectricalengineering
2⃣Direct Current (DC): This symbol indicates that the meter is set to measure direct current. It is usually represented by a straight line with a dashed line below it, indicating the flow of current in a single direction.
3⃣Alternating Current (AC): This symbol represents the measurement function for alternating current. It is typically denoted by a wavy line, indicating the periodic oscillation of current flow.
4⃣Resistance (Ω): The symbol for resistance is the Greek letter omega (Ω). It represents the measurement function used to measure the resistance of a component or circuit.
5⃣Continuity: This symbol indicates the continuity measurement function. It is represented by a sound wave symbol (∞) or an audible speaker symbol. It is used to test if a circuit or component has a continuous path for current flow.
6⃣Diode Test: This symbol is used for the diode testing function of the multimeter. It is often depicted as an arrow pointing towards a vertical line with an arrowhead.
7⃣Capacitance (F): The symbol for capacitance is "F" and represents the measurement function used to measure the capacitance of a capacitor.
8⃣Frequency (Hz): The symbol for frequency is "Hz" and represents the measurement function used to measure the frequency of a periodic signal.
9⃣Duty Cycle (%): The symbol for duty cycle is represented by a percentage sign (%). It is used to measure the ratio of the active time of a periodic signal to the total period.

| 19 | 💡A light-dependent resistor (LDR), also known as a photoresistor, is an electronic component that exhibits a change in resistance when exposed to light. The resistance of an LDR decreases as the intensity of light increases and increases as the intensity of light decreases.
@theelectricalengineering
➡LDRs are made of a semiconductor material, such as cadmium sulfide, that is sensitive to light. When light falls on the surface of the semiconductor, the photons in the light excite electrons in the material, which causes the resistance of the material to decrease. Conversely, when there is little or no light, the electrons in the material are not excited, and the resistance of the material is high.
➡LDRs are often used in light-sensing applications, such as automatic streetlights, light meters, and camera exposure controls. In an automatic streetlight, for example, an LDR can be used to detect the ambient light level and switch the streetlight on when it gets dark and switch it off when it gets light.
➡LDRs can also be used in conjunction with other electronic components, such as transistors or operational amplifiers, to create more complex circuits. For example, an LDR and a transistor can be used to create a light-controlled switch that turns on a light or other device when it gets dark.
➡In summary, an LDR is an electronic component that exhibits a change in resistance when exposed to light, and is commonly used in light-sensing applications such as automatic streetlights, light meters, and camera exposure controls.
