Current is a measure of how much electric charge flows ... A circuit diagram showing a voltmeter in parallel with a lamp When two components are connected in parallel, you cannot follow the ...

Voltage is measured in volts, V, with a voltmeter. Voltmeters are always connected in parallel. This is because it is measuring the difference in energy between the two points it is connected across.

You can use a voltmeter and an ammeter, but it is very straightforward if you have a four-channel scope with a pair of current probes. Of course, if you can measure the voltage and the current at ...
