Resistors are passive digital elements that limit the stream of electrical present in a circuit. They’re used to manage the voltage and present in a circuit, and can be utilized to create quite a lot of digital units. Resistors can be found in a variety of values, and can be utilized in each AC and DC circuits.
Testing resistors is a crucial a part of making certain that they’re functioning correctly. Resistors can fail for quite a lot of causes, together with overvoltage, overcurrent, and warmth harm. Testing resistors can assist to determine failed resistors and forestall them from inflicting harm to different elements in a circuit.
