Resistors are passive electronic components that restrict the flow of electric current in a circuit. They are used to control the voltage and current in a circuit, and can be used to create a variety of electronic devices. Resistors are available in a wide range of values, and can be used in both AC and DC circuits.
Testing resistors is an important part of ensuring that they are functioning properly. Resistors can fail for a variety of reasons, including overvoltage, overcurrent, and heat damage. Testing resistors can help to identify failed resistors and prevent them from causing damage to other components in a circuit.
