Water in a Reservoir to Electricity in a Home
Water flows through a channel underground to
make the blades of the turbine spin which turns the
generator. This changes mechanical energy into
electrical energy.
Electricity leaves the power plant by wires and
travel to a substation.
Step- up transformers increase the voltage to travel
down wires to homes and businesses.
Step – down transformers lower the voltage before
coming into homes.
Wires connect to junction boxes – which connect to
outlets. Electricity then travels a circuit to your
television etc.
