When the second bulb is added, they get
brighter
dimmer
broken
cold
What is the measuring device shown?
bulb
cell
ammeter
voltmeter
What can you say about the current in the series circuit?
it splits across the components
it changes constantly
it is different in different places
it is the same everywhere
Which component provides the energy for the charges?
cell
bulb
switch
ammeter
If the ammeter says the current is 5A, what is the current flowing through one bulb?
2.5A
10A
5A
0
If one bulb was broken, what would happen?
current would no longer flow, so everything would be off
the ammeter would measure a current from the other bulb
the switch would keep the current flowing
the cell would burn out and catch fire
What is the name of the device which measures current?
(a)
Current is measured in
Volts
Watts
Seconds
Amps
If the switch was opened, what would happen?
the ammeter would measure a current flowing
current would no longer flow, so everything would be off
the bulbs would stay on because they're connected to the cell
the bulbs would burn out and catch fire
Name the charged particle, which is part of an atom, that flows in a circuit
proton
electron
neutron
elepton
What causes a decrease in current?
Adding another bulb
increasing resistance
decreasing voltage from the supply
decreasing the resistance
If the current flowing through the cell is 2A, what is the ammeter reading?
5A
1A
6A
2A
What is the unit of measurement for resistance?

Which one is a series circuit?
Which one is a parallel circuit?
What happens to the current in a series circuit?
The current stays the same
The current is added
The current is reduced
The current is split between the light bulbs
What happens to the current in a parallel circuit?
The current stays the same
The current is added
The current is reduced
The current is split between the light bulbs
What happens to the voltage in a series circuit?
The voltage stays the same
The voltage is added
The voltage is reduced
The voltage is split between the light bulbs
What happens to the voltage in a parallel circuit?
The voltage stays the same
The voltage is added
The voltage is reduced
The voltage is split between the light bulbs
What is resistor?
Electrical component that is specially made to have a specific resistance
The measure of the difference in how much energy the electrons receive to move around at different points in a circuit
The flow of electrical charges
The movement or presence of electrons
Why voltage is important?
Because it is the pressure that causes the electrons to move around in a circuit and make the current flow and make appliances work
To supply energy to be able to make the current flow in electric circuit and make appliances work
To control the resistance in the circuit
To reduce the current in the circuit
What is the unit used for voltage?
Ampere
Ohm
Volt
Meter
