Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

Calculating Series Voltage Drop Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string ...

In National 4 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.

The series circuit is a single closed loop, as you can see. But a parallel circuit provides multiple loops. If you stack the loads on top of each other ladder-rung-style in your drawing, they are in ...
