The answer to 'difference between troubleshooting' is that troubleshooting is the process of identifying and resolving issues or problems with electrical systems, while testing is the systematic evaluation of electrical components and circuits to verify their proper operation. Troubleshooting typically involves a more hands-on, investigative approach to diagnose and fix issues, while testing is a more methodical process of checking for proper functionality.
Troubleshooting often involves using a multimeter, visual inspection, and logical troubleshooting steps to isolate the source of the problem, while testing may involve using specialized equipment like ammeters, voltmeters, and other tools to measure and verify the performance of electrical components and circuits.
