• Series Parallel

2
What type of circuit is this?
Series Circuit-
has only one path for electrons to flow.
3
What are the different parts of a circuit?
Energy Source
Energy source is the device that powers the
circuit.
The basic unit of force is
Voltage.
Amperes (amps).
Current flow is measured in
4
What are the different parts of a circuit?
Control Device
Energy Source
The Control Device opens and closes a circuit.
An open circuit doesnt work a closed circuit
could work.
5
What are the different parts of a circuit?
Control Device
Energy Source
Load
The Load changes the energy of moving electrons
into some other useful form of energy. It is the
purpose of the circuit.
