How does current behave in series circuits?
The current is the same at each position around the circuit.
The current from the power supply is shared between the components.
The current is largest at the first component and decreases as it passes through each component.
The current in the circuit is higher than the current in the components.
How does potential difference behave in series circuits?
Potential difference of the components adds together to equal the potential difference of the power supply.
Potential difference is the same for all components in a circuit.
Potential difference is largest at the first component and decreases as the current travels around the circuit.
Potential difference of each individual component is the same as the potential difference of the power supply.
What is the rule for resistance in a series circuit?
Resistance in series adds up.
Resistance in series is the same at all points of the circuit.
Resistance is always highest at the first component the current passes through.
Resistance is always lowest at the first component the current passes through.
How does current behave in parallel circuits?
The current of the individual branches adds up to equal the current of the main branch of the circuit.
The current of the individual branches is the same as the current in the main branch of the circuit.
The current of the individual branches is more than the current in the main branch of the circuit.
How does potential difference behave in parallel circuits?
Potential difference of each branch is the same as the potential difference of the power supply.
Potential difference of each branch is higher than the potential difference of the power supply.
Potential difference of each branch adds up to equal the potential difference of the power supply.
What is the rule for resistance in parallel circuits?
Resistance is lower than the value of an individual resistor.
Resistance adds up.
Resistance is shared equally between the components.

The potential difference and current stay constant.
In the required practical for resistance in a wire, what are the expected results?
As length of wire increases, resistance increases at the same rate.
As length of wire increases, resistance decreases.
As length of wire increases, resistance remains constant.

State the equation that links charge flow, current and time
Charge = current x time
Charge = current ÷ time
Time = current x charge
Current = time x charge
State the equation that links current, potential difference and resistance.
Voltage = current x resistance
Resistance = voltage x current
Current = resistance x voltage
State the equation that links current, potential difference and power.
Power = potential difference x current
Current = potential difference x power
Potential difference = power x current
