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, ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

If you’d like to fix or even diagnose anything involving electricity – whether it’s the energy that surges through a car, snowmobile, boat or even a wall socket or a random AAA remote control battery ...

While it's often best to call an electrician if you suspect you have a dangerous electrical issue, you can also safely diagnose many of those problems yourself with a multimeter, which is why it's ...

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.

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

The first time I used a multimeter was in my younger years. I was really into remote-controlled cars—but you couldn't just buy one and start driving. You had to buy a kit and a controller separately ...

I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.
