Question

A Resistor with a current of 3A through it converts
500J of electrical energy to heat energy in 12 sec.
what is voltage across resistor.​

Answer 1

Answer:

voltage = 13.88 V

Explanation:

Refer to the picture

Answer 2

Answer:

    13.88V

Explanation:

Given:

    Current,I=3A

    Energy,E=500J

    Time,t=12sec

Formula:

    Energy, E = VIt

Solution:

    E = V*I*t ====> 500 = V*3*12

                              V = 500/(3*12)

                                  = 500/36

                                  = 13.888888888888V
