Electrical Circuits

Open Ended

These birds are perched on a power line. Why do you think they aren't being electrocuted?

Electricity is the flow pf electric power or charge.

Electricity is present in nature, and humans generate it for heat, light, and power.

​

​Electricity

It is a closed loop or path where the charged particles can move through a conductor, to a load by utilizing electromagnetic fields.

An electric current is the flow of electric charge in a circuit.

​

Electrical Circuit

1) energy source - provides the voltage (force that pushes electrons) and the current (rate of flow of electrons)

2) conductor - allows electrons to flow

3) load - uses the electrical energy

4) switch - controls the electric current

​

Basic Components

Multiple Choice

Which part of a circuit controls the electric current?

• source

• conductor

• switch

Multiple Choice

Which part of a circuit provides the voltage and the current?

• source

• load

• conductor

Open circuit - when the components of a circuit is incomplete, and there is no circuit.

Closed circuit - when the circuit forms a complete path and the electricity flows to the desired endpoint.
