Parallel Circuit with a Switch
A circuit contains a battery and two resistors connected in parallel. A switch is installed to connect a third resistor in parallel with the other two. Which statement correctly compares the circuit when the switch is open to when it is closed?
A
The switch position has no effect on whether the circuit is closed
B
Only the configuration with the switch closed is a closed circuit
C
Both configurations represent closed circuits with different equivalent resistances
D
Opening the switch creates an open circuit in all branches
