Q: When switch S in the figure (Figure 1) is open, the voltmeter V of the battery r

Part (a) Emf, E = 3.09 V Part (b) I = 1.66A When switch is closed, V = E - I*r = 2.95 V 3.09 - 1.66*r = 2.95 r = 0.0843 Part (c) I*r + I*R = E I * (r+ R) = E 1.66 * ( 0.084 + R) = 3.09 R = 1.77

Question

When switch S in the figure (Figure 1) is open, the voltmeter V of the battery reads 3.09 V . When the switch is closed, the voltmeter reading drops to 2.95 V ,and the ammeter A reads 1.66 A . Assume that the two meters are ideal, so they don't affect the circuit.

Explanation / Answer

Part (a)
Emf, E = 3.09 V

Part (b)
I = 1.66A
When switch is closed, V = E - I*r = 2.95 V
3.09 - 1.66*r = 2.95
r = 0.0843

Part (c)
I*r + I*R = E
I * (r+ R) = E
1.66 * ( 0.084 + R) = 3.09
R = 1.77
