(a)
The effect on the voltage across each resistor when the switch is closed.
(a)

Answer to Problem 19P
The voltage across resistor
Explanation of Solution
Introduction:
The current in the circuit varies with the resistance of the circuit. If the resistance increase then the current decreases.
The resistors of the resistance
When the switch become closed then the equivalent resistance of the parallel resistors
Conclusion:
Therefore, the voltage across resistor
(b)
The effect on the current through each resistor.
(b)

Answer to Problem 19P
The current through resistors
Explanation of Solution
Introduction:
The current in the circuit varies with the resistance of the circuit. If the resistance decreases then the current increases.
The equivalent resistance of the circuit decreases due to closing of the switch, so the current drawn from the battery increases.
The resistor
The equivalent resistance of the parallel connection decreases due to addition of the resistor in parallel connection with closing of the switch. The current through resistors
Conclusion:
Therefore, the current through resistors
(c)
The effect on the power output of the battery due to closing of switch.
(c)

Answer to Problem 19P
The power output of the battery increase due to closing of switch.
Explanation of Solution
Introduction:
The power of the circuit varies with the resistance of the circuit. If the resistance decreases then the power of the circuit increases.
The equivalent resistance of the circuit with open switch is greater than the equivalent resistance with closed switch. The equivalent resistance of the circuit becomes less on closing of switch due to addition of the resistor
Conclusion:
Therefore, the power output of the battery increase due to closing of switch.
(d)
The current through each resistor before and after closing the switch.
(d)
