How To Test Resistor

by

Most electrical circuits use resistors to limit the flow of current. Resistors can fail or change value over time, which can cause problems in the circuit. Testing a resistor is a simple and safe process that can be done with a few basic tools. The most common type of resistor is a carbon composition resistor. … Read more

1. How to Check Ohms Using a Multimeter

Measuring Ohms with a Multi-meter is a fundamental skill for any electrician. Ohms are the measure of resistance to the flow of electrical current, and Ohms law (V = I * R) shows that resistance is directly proportional to voltage and inversely proportional to current. Whether you’re troubleshooting a circuit or simply verifying that a … Read more
