A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician's tool kit. Every DMM is slightly different but there are some general guidelines you can follow for its use. An old analog voltmeter will work too but be careful of polarity when using one ...
and works like a voltmeter: it measures the voltage (electrical potential) produced by the solution whose acidity we're interested in, compares it with the voltage of a known solution, and uses the difference in voltage (the "potential difference") between them to deduce the difference in pH...

What is a moving coil galvanometer ? Explain in detail. Explain the basic concept of electric current. Discuss the meaning of the polarity of a voltmeter and of an ammeter. How can you explain work, in regards to electricity? How is the working of a power station generator connected to el...
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 workin...
I had the idea to use a 220v 4kw speed controller into a high power bridge rectifier and happy days, it seems to work well to power the machine. I would have preferred a digital voltmeter (on the panel that houses the components), but had trouble finding one. There was a 0-450v ...
Running a load test on your car's alternator using a voltmeter or multimeter could help you figure out if your alternator is on the fritz. Tricky_Shark/Shutterstock With so many components working to create the electricity vital for our vehicles, it's safe to say the alternator is a cruci...

If you hook that second coil of wire to a voltmeter, you can actually see the needle or readout change whenever you connect or disconnect the wires from the battery. That's because exposing a coil of wire to a changing magnetic field can induce electricity to flow through that wire. The...
