It is relatively easy to measure amps to determine the amount of power an appliance or load uses, but the measurement must be done accurately to avoid damaging your multimeter. Multiplying the voltage in a circuit, with the current flowing in the circuit, will give us the total power in the...
How to measure current with a digital multimeter Though the process of using a digital multimeter to measure current is fairly simple, it’s slightly more difficult than using a digital multimeter to measure voltage or resistance. That’s because to measure current, you need to break the circuit...

Write down the current reading from the multimeter screen and start the stopwatch. If the reading is in amps, multiply by 1000 to convert to milliamps. For example, assume the current reading was 200 milliamps. 5. Stop the timer when the device being power by the battery shuts off. The...
To measure battery load, conduct three voltage tests with the multimeter. Start the first test by making sure the vehicle is turned off. Multimeters have two probes: red and black. The red probe is for contact with the positive terminal and the black probe is for contact with the negative ...
An amp is the unit used to measure current in an electrical system. There are several ways to calculate amperage using other units of electricity, including watts, volts, and ohms. In this article, we’ll look at what an amp is, the formula to calculate amps, and why knowing how to de...
In this tutorial, we're going learn how to use a multimeter! A multimeter is one of the best tools around the shop for testing electronics and circuits!
It's a must-have for any toolbox—but there's a learning curve involved. Learn how to use a multimeter for all of your electrical testing needs.
Though it’s not uncommon to measure current with a digital multimeter, measuring current that changes over time requires the use of an oscilloscope. Most oscilloscopes only directly measure voltage, not current, however you can measure current with an oscilloscope, using one of two methods. ...
Learn the basics of using a multimeter to measure continuity, voltage, resistance and current. We highly recommend having a DMM in your electronics toolbox. It's great for measuring current or voltage.Connections How Do I Connect My Battery or Power Supply to My Circuit? There are many ways...
