Question

A complete series circuit consists of a 12.0 V battery, a 4.72 Ohm resistor, and a switch. The internal resistance of the battery is 0.360 Ohm What does an ideal voltmeter read when placed across the terminals of the battery? The switch is open. What does an ideal voltmeter read when placed across the resistor? The switch is open. What does an ideal voltmeter read when placed across the switch? The switch is open. What does an ideal voltmeter read when placed across the terminals of the battery? The switch is closed. What does an ideal voltmeter read when placed across the resistor? The switch is closed. What does an ideal voltmeter read when placed across the switch? The switch is closed.

Explanation / Answer

According to the question provided I can see multiple sub parts and I am allowed to answer only 4 sub parts at a time According to the chegg guidelines.

when the switch is opened ideal voltmeter has zero current flow.

Part a) When placed across the terminals of the battery.

answer) it will read 12 Volts ====answer)

Part b) when placed across the resistor.

answer) It will read = 0 Volts ===answer)

Part c) when placed across the Switch.

answer) It will read = 12.0 Volts ==answer)

Part d) when the switch is closed (across the terminals of the battery.)

answer) when switch is closed current flow so ,

V(1) = 12.0 V - ( 2.5423 * 0.360 ) = 11.084772 Volts ===answer)
