In this hands-on introduction to electronics, you will experiment with a multimeter and learn how to measure current using the ammeter function. Project Overview In this project, you will learn how to use an ammeter to measure electrical current (the flow of electricity). Typically, the ammeter...
A multimeter is a measurement tool absolutely necessary in electronics. It combines three essential features: a voltmeter, ohmeter, and ammeter, and in some cases continuity. A multimeter allows you to understand what is going on in your circuits. Whenever something in your circuit isn’t working...

Step 3: Testing the control with a volt-ohm-milliammeter (VOM) is not recommended, because the results will not always be conclusive. If you suspect that the setting control is faulty, the best procedure is to substitute a control that you know is working, or you could simply replace the...
When a multimeter is used as an ammeter, it will measure the amount of current that passes across the circuit being tested. In order to use the device in this manner, the multimeter has to be connected in series with the circuit in order to measure the amperage of the electricity passing...
butthe simplest way to measure direct current (DC) is by using a digital multimeter A gap is made in the circuit and is connected to a digital multimeter (DMM) so that it becomes part of the circuit itself. The current passes through the DMM, which displays the measurement on the display...
The remaining resistors, capacitor, and milliammeter can be junk box items. The diode is non-critical, a 1N914 / 1N4148 type should be fine. A 1N34 would be better in theory, but most any small signal diode should work. 1N914 datasheet If you want to use this with higher power, ...
We used an in-line USB Ammeter and calculated wattage (although some meters may show the wattage as well). This was connected between the power bank and the router. Test Results & Devices Breakdown: * The power range indicates idle vs active doing a speed test on USB-C PD 12V direct op...
How To Read An Ohm MeterTechnology ElectronicsHow To Read An Ohm MeterBy Christopher Donahue Updated Mar 24, 2022 The ohm meter is one of the most basic pieces of electronic test equipment. It is often a range of settings on a multimeter (volt-ohm-milliammeter or VOM) as the ohm ...
