Resistance in Parallel Circuits Flashcards
1
Q
How do we calculate the total current?
A
Total current is the sum of the currents through the separate components
2
Q
How do we calculate potential difference?
A
PD is the same across each component
3
Q
What is the correlation between resistance and current?
A
The bigger the resistance at a component, the smaller the current that will pass through the component
4
Q
What is the equation to calculate current in a parallel circuit?
A
V
I _
R
5
Q
What happens when we add more resistors?
A
The total resistance will decrease because the total current through the resistors is increased and the PD across them is unchanged.
