Power and Series Circuits: The electrical power formula is introduced and students learn how to use Ohm’s Law and the power formula to solve problems. They also learn to draw diagrams for series ...

The methods used to analyze series and parallel circuits can be combined to analyze these series-parallel circuits. Series-parallel circuit. The Figure at right shows three impedances; two are ...

Circuit diagrams – Diagrams which help to visualise and understand how components are connected in a circuit. Symbols – Simplified drawings of electrical components.

Different models, such as water flowing in a central heating system, can be used to understand electrical circuits. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

As with series circuits containing resistances, inductances, and capacitances, if the inductive reactance of a parallel circuit equals the capacitive reactance, the circuit is said to be resonant at ...
