Three requirements of a complete
circuit
4
Source of Electricity
5
2. Load (something which uses energy)
6
3. Needs a Path to get the energy from source to
load and back
7
Millions of small particles called
ELECTRONS are moving at random (without direction
or pattern) while the circuit is open.
8
When the switch is closed the ELECTRONS flow
through the wires from the battery, to the
switch, to the lamp, and back to the battery.
9
When the circuit is complete or closed
electrons flow through the wires from NEGATIVE to
POSITIVE.

SWITCH provides a simple way to open and
