What do series and parallel circuits have to do with Christmas ... Then, using Ohm's Law, you can calculate the voltage across, and current through, each resistor. OK, let's do the easiest steps ...

You can investigate voltage across cells and lamps in a series and parallel circuit by connecting the following circuits. Put one voltmeter in position V 1 and record the reading in a suitable table.

are electronic components that can be used to regulate the voltage ... parallel circuits. They also discuss the differences between current and resistance across different circuits and how to ...
