Equivalent resistance for resistors in parallel for 2 resistors:
Equivalent resistance for resistors in series:
Relabel the resistors as:
In the circuit at right, the battery has a voltage of 6.0 V, and the two resistors have resistance 20 Ω each.
(a) What is the current in the circuit and the potential difference across the 10 Ω resistor when the switch is open?
(b) When the switch is closed?
