Parallel Circuits Summary

GCSE Physics

A circuit is a loop of wire with its ends connected to an energy source.

GCSE Physics

One end of the wire is connected to the positive terminal; the other end of the wire is connected to the negative terminal.

GCSE Physics

Parallel circuits have their components lying inside "parallel" loops connected to the same energy source. For example:

Two lamps in parallel

GCSE Physics

Failure of one component in a parallel circuit does not lead to the failure of the other components.

GCSE Physics

The more components connected in parallel, the more energy is used.

GCSE Physics

The total current flowing from a cell in a parallel circuit equals the sum of all the currents flowing in the loops.
