Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

About Those Series and Parallel Circuits Resistors, capacitors and inductors are easy once you understand the basics ...

A tip for quick calculation – when all resistors are the same value, their equivalent resistance is their value divided by the number in of parallel resistors. Break the circuit down into small pairs ...

This tip is useful in simplifying transformer equivalent circuits or filter networks down to two terminal devices. Figure 1 shows the transformation equations for converting a parallel circuit into a ...

In National 5 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.
