Suppose we connect the terminals of battery $A$ with a single uniform wire with a certain length. Suppose we connect the terminals of an identical battery $B$ with a single uniform wire with the same length and diameter but a lower conductivity. Specify whether each of the following quantities is $(A)$ greater in the circuit connected to battery $A,(B)$ greater in the circuit connected to battery $B$, or (C) the same in both circuits.
-(d) The potential difference $|\Delta \theta|$ between the wire's ends
A) A
B)B
C)C

Question

Quizplus · Accepted Answer

The potential difference $|\Delta \theta|$ between the wire's ends is determined by the battery's voltage, not the wire's conductivity. Since both circuits are connected to identical batteries, the potential difference across the wires will be the same in both circuits.
