Same through all parts of the circuit
How can you switch components in series circuits?
How can you switch components in series circuits?
Can only switch all off at once
How is PD distributed in series circuits?
How is PD distributed in series circuits?
Shared across the whole circuit
What is the total resistance in series circuits?
What is the total resistance in series circuits?
Sum of the resistance in each component
Why is resistance bigger in series circuits?
Why is resistance bigger in series circuits?
Charge has to push through all components
How are components connected in parallel circuits?
How are components connected in parallel circuits?
Separately to the power supply
How can you switch components in parallel circuits?
How can you switch components in parallel circuits?
Can switch each component off individually
How is PD distributed in parallel circuits?
How is PD distributed in parallel circuits?
Same across all branches
How is current distributed in parallel circuits?
How is current distributed in parallel circuits?
Shared between each of the branches
What is the total resistance in parallel circuits?
What is the total resistance in parallel circuits?
Less than the branch with the smallest resistance
Why is resistance smaller in parallel circuits?
Why is resistance smaller in parallel circuits?
Charge has more than one branch to take, so it's shared
