Consider the circuit shown.(Figure 1) All wires are considered ideal; that is, they have zero resistance. We will assume for now that all other elements of the circuit are ideal, too: The value of resistance R is a constant, the internal resistances of the battery (r) and the ammeter (RA) are zero, and the internal resistance of the voltmeter (RV) is infinitely large.

Question 1: What is the reading V of the voltmeter?

Question 2: The voltmeter, as can be seen in the figure, is connected to points 1 and 3. What are the respective voltage differences between points 1 and 2 and between points 2 and 3?

Question 3: What is the reading I of the ammeter? Express your answer in terms of E and R

Question 4: What is the reading of the ammeter now? Express your answer in terms of E, r, and R.

Question 5: What is the reading of the voltmeter now?Express your answer in terms of E, r, and R.
