Part I
The voltmeter is now removed and a 21.0-ohm resistor is connected to the terminals of the battery. What is the current I through the battery? Express your answer in amperes. Use two significant figures.
Part J
In the situation described in Part I, what is the current I through the 21.0-ohm resistor? Express your answer in amperes. Use two significant figures.
Part K
What is the potential difference V across the 21.0-ohm resistor from Part 1? Express your answer in volts. Use three significant figures.
Part L
What is the terminal voltage V of the battery connected to the 21.0-ohm resistor from Part I? Express your answer in volts. Use three significant figures.
