a building at the fuse box. Excess electricity flow is controlled by a fuse.
The electric current
flows through cables. The cable contains two or three wires.
The electricity can be
used by ‘plugging in’ an appliance into a socket using a plug. You switch on
the socket to use it and you switch off when you have finished.
The electrician will
wire up the building, so lights can be controlled from a light switch.
Table lamps are
generally switched on at the lamp itself which is plugged into a socket on the
wall.
The lights work
because they have light bulbs. When light bulbs are exposed to electricity,
they glow.
Light bulbs are sold
by how many watts they consume: 40, 60, or 100. Today we have energy saving bulbs
that use a lot less electricity than traditional ones.
