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? ** Awners are either (0;E), (0;?E), (E; 0) or (E;E)
Question 3: What is the reading I of the ammeter? Express your answer in terms of E and R
What is the reading of the ammeter now? Express your answer in terms of E, r, andR.
What is the reading of the voltmeter now?Express your answer in terms of E, r, andR.
