1
Q
what is current?
A
current is the rate of flow of charge
2
Q
what is potential difference?
A
potential difference is the work done in moving a unit charge
3
Q
what is ohms law?
A
provided that physical conditions (like temperature) remain constant, the current is proportional to potential difference
4
Q
how do current and potential difference act in a parallel circuit?
A
current splits depending on the resistance in each branch
voltage is constant everywhere
