A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Part of Design and Technology Electronic and microelectronic control systems Using Ohm’s Law (V=ꞮR), you can calculate the expected values for voltage, current, and resistance in a circuit. Ohm's law.

This multimeter add-on is called the Half Ohm. It allows you to measure small resistance values, and can be used to track down shorts on a PCB. The board acts as a pass-through for both probes. When ...
