Energy Consumption in Parallel Circuits

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

For example, if each of the circuits on this page used the same type of cell* and same type of lamp...

...the circuit below would light one lamp for 12 hours:

One lamp in series

...the circuit below would light two lamps for 6 hours:

Two lamps in parallel

...and the circuit below would light three lamps for 4 hours:

Three lamps in parallel
