The answer to 'types of troubleshooting' is that there are several common approaches electrical technicians use to identify and resolve issues in home electrical systems. The most common types of troubleshooting include visual inspection, testing with a multimeter, tracing circuits, and isolating components.
Visual inspection involves carefully examining the electrical components, wiring, and connections for any obvious signs of damage, wear, or improper installation. Testing with a multimeter allows technicians to measure voltage, current, and resistance to identify problems. Circuit tracing involves following the flow of electricity through the system to locate the source of an issue. Isolating components means testing individual parts to determine if they are functioning properly.
