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

This circuit contains a 5 Ω resistor in series with two resistors, 6 Ω and 4 Ω, which are in parallel. Start by calculating the combined resistance of the two parallel resistors.

This C project helps you analyze electrical circuits by calculating voltage, power, and total power for a given set of resistances and currents. It works with both series and parallel circuits and ...
