Look at the data for circuit 1 and circuit 5 both circuits have the same voltage but different currents. Explain why?

The current in a circuit is determined by the resistance of the circuit. Circuit 1 has a higher resistance than Circuit 5, so the current in Circuit 1 is lower than the current in Circuit 5. This is because the higher the resistance, the more the voltage is divided across the circuit, resulting in a lower current.
