Diode Testing
Diode Testing is a basic but important skill in electronics repair where technicians check if small electronic components called diodes are working correctly. It's similar to checking if a one-way valve in plumbing is working - diodes should only let electricity flow in one direction. Repair technicians use this skill when fixing everything from TV sets to computer power supplies. This testing is usually done with a simple tool called a multimeter, which is like a digital thermometer but for electronics.
