Question

Part A

When the switch is closed in the circuit shown in the figure(Figure 1) , does the current supplied by the battery increase, decrease, or stay the same?

Part B

Choose the best explanation from among the following:

- Closing the switch makes no difference to the current because the voltage is the same as before. - The current increases because three resistors are drawing current from the battery when the switch is closed, rather than just two. - Closing the switch decreases the current because an additional resistor is added to the circuit.

Explanation / Answer

A) CURRENT SUPPLIED BY THE BATTERY INCREASES

B) The current increases because three resistors are drawing current from the battery when the switch is closed, rather than just two.
