Question

Parts A-D pertain to the circuit at the bottom.

Part A) What happens to the voltage across R1 when the switch is closed?

A) V1 increases. B) V1 remains the same. C) V1 decreases. D) not enough information to tell

Part B) What happens to the voltage across R3 when the switch is closed?

A) V3 increases. B) V3 decreases. C) V3 remains the same. D) not enough information to tell

Part C) What happens to the current through R2 when the switch is closed.

A) I2 increases. B) I2 decreases. C) I2 remains the same. D) not enough information to tell

Part D) What happens to the power output of the battery when the switch is closed?

?A) the power output increases. B) the power output decreases. C) the power output remains the same. D) not enough information to tell

Part A) What happens to the voltage across R1 when the switch is closed?

Answer: total current will increase as a parallel branch comes into picture, therefore voltage increases.

Part B) What happens to the voltage across R3 when the switch is closed?

Answer: Same reason as above, voltage will increase.

Part C) What happens to the current through R2 when the switch is closed?

Answer: Current increases

Part D) What happens to the power output of the battery when the switch is closed?

Answer: Power output will be more, since current increases.

Power = voltage times current

Voltage of the battery is constant, current increases, so does the power.
