A complete circuit consists of a 24.0 Volt battery, a 5.60 ohm resistor, and a switch. The internal resistance of the battery is 0.28 ohm. The switch is open (no current is flowing).
A) Find what does an ideal voltmeter read when located across the resistor?
B) Find what does an ideal voltmeter read when located across the switch?
C) Now the switch is closed. What does an ideal voltmeter read when located across the terminals of the battery?
D) Find what does an ideal voltmeter read when located across the resistor?
E) Find what does an ideal voltmeter read when located across the switch?
