Some metal conductor has a resistance of 12 ohms. When plugged into a circuit, the amount of heat 144J is released in 12s. What

worty [1.4K]

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 = $\frac{work done }{time}$

= $\frac{144}{12}$

= 12W

Electrical power is given as;

P = IV = $\frac{V^{2} }{R}$

Since V is the unknown, we solve for it;

12 = $\frac{V^{2} }{12}$

V = 12V
