Resistors are passive digital elements that limit the stream of electrical present in a circuit. They’re used to regulate the voltage and present in a circuit, and can be utilized to create a wide range 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 vital a part of making certain that they’re functioning correctly. Resistors can fail for a wide range of causes, together with overvoltage, overcurrent, and warmth injury. Testing resistors can assist to establish failed resistors and forestall them from inflicting injury to different elements in a circuit.
