Testing electronic components is a crucial step in electronics troubleshooting and repair. Here's a list of 20 common electronic components along with DIY testing methods for each:

1. Resistor:

• Use a multimeter in resistance (ohms) mode to measure the resistance value.

2. Capacitor:

• Use a capacitance meter or a multimeter with a capacitance setting to measure capacitance.

3. Inductor:

• Check for continuity using a multimeter. The inductor should have low resistance.

4. Diode:

• Use a multimeter in diode mode to check forward and reverse bias. A good diode should allow current in one direction only.

5. LED (Light-Emitting Diode):

• Test with a multimeter in diode mode. An LED should light up when forward biased.

6. Transistor:

• Test using a multimeter's diode mode for bipolar transistors (NPN/PNP). Check for continuity and proper voltage drops.

7. Zener Diode:

• Test in the reverse bias direction using a multimeter. A Zener diode should exhibit a stable voltage drop.

8. Schottky Diode:

• Test similar to regular diodes. Schottky diodes have lower forward voltage drops.

9. Photocell (LDR - Light Dependent Resistor):

• Measure resistance in both dark and light conditions using a multimeter.
