a word for a source of energy to push electricity around a circuit.
cell
a word for the flow of charged particles
current
How many terminals does a cell have? What are they?
two/a positive and a negative terminals
If we put the two positive terminals of the cells in a torch together, will the bulb light up? Why?
No .because the electric current cannot flow round the circuit.
What is the function of a cell?
pushes electric current around a circuit.
What kind of the components do we need to make a simple circuit?
cell/ s bulb or lamp or a bulb holder/ copper wire covered in plastic
What happened to the bulb when you break the circuit?
The bulb does not light up.
What happened the bulb if you close a switch in a complete circuit?
the bulb light up because electric current flow around the circuit.
Look at the picture . When you add more bulbs to the circuit, what happened the bulbs?
Bulbs shine less brightly.
Look at the picture. If you use too many cells in the circuit, what happened the bulbs?
the bulbs pop or burn out.
a word for a component that makes a buzzing noise when the circuit is complete.
buzzer
Unit for the strength of electricity.
volt
Look at the picture. Each cell has 1.5 V and a buzzer has 3 V. How did the buzzer work when you had two cells in the circuit?
Buzzer can be able to work because it has a certain strength of electricity.
What is voltage?
the strength of the electricity
a word for hole in the wall that link the plug on an appliance to the cables going to the electricity source
wall socket
How many votes does the mains electricity have?
110V/220V
