Electricity flows in circuit

Investigate a torch

Open Ended

If you turn on the torch what do you think will happen?

What is inside the torch?

What do you think makes the light shine?

Investigate a torch

The torch will shine. The torch works because each cell/battery pushes the electricity. This makes the bulb light up.

Cell

A cell is a source of energy to push electricity around a circuit.

What is electricity?

An electricity is the flow of charged particles.

Electricity can flow in one direction.

We call this electrical current.

Multiple Choice

A source of energy to push electricity around a circuit called ..............

• cell/battery

• switch

• lamp

• motor

Components

The bulb and the cell in a torch are each a component of a circuit.

Complete circuit

Current needs a continuous path. This path is called a complete circuit.

A complete circuit is a circuit where the electrical current can flow all the way around.

Multiple Choice

Which of these circuits can make the bulb light up?

Open Ended

Daniel connects the electrical circuit for 10 days. After 10 days the lamp does not work.

Why the lamp does not work?

Switches

Closing a switch completes a circuit and allows electric current to flow.

Switches

Opening the switch breaks the circuit, This means the current will not flow,

Multiple Select

Dimas makes an electrical circuit.

The lamp does not work. Why?

Choose the two correct reasons.

• The circuit is not complete

• There is no cell in the circuit

• There is no motor in the circuit

• The switch is on

• The switch is off
