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.
