Electricity

Question 1

What happens when resistors are connected in a series?

Answer 1

The current through each resistor is the same and the total voltage (or potential difference) across all the resistors is equal to the sum of the voltages across each resistor

Question 2

What happens when resistors are connected in a parallel circuit?

Answer 2

The supply current is equal to the sum of the currents through each resistor and they have the same potential difference across them

Question 3

How do you calculate 2 resistors in a parallel circuit, what equation?

Answer 3

1/R = 1/R1 + 1/R2
