Answer:
12V
Explanation:
Given parameters:
Resistance = 12ohms
Heat released = 144J
Time taken = 12s
Unknown:
Voltage at the ends of the conductors = ?
Solution:
To solve this problem, we must first determine the power expended by the circuit.
Power is the rate at which work is done;
P =
=
= 12W
Electrical power is given as;
P = IV =
Since V is the unknown, we solve for it;
12 =
V = 12V
