Question

The energy transfer to a device is 112,000 J when there is a potential difference of 185 volts across it. The charge moved is...

a) 604.32 C
b) 730.88 C
c) 605.41 C
d) 604.86 C

Answer 1

To find the charge moved when energy is transferred to a device, divide the energy by the potential difference. The answer, in this case, is 605.41 C.

Step-by-step explanation:

The student asks about the charge moved when there is an energy transfer to a device, giving the energy and the potential difference. To calculate the charge moved (Q), we use the formula:

Energy (E) = Charge (Q) × Potential Difference (V)

We rearrange the formula to solve for Q:

Q = E / V

Substituting the given values:

Q = 112,000 J / 185 V = 605.41 C

Therefore, the charge moved is 605.41 C, which corresponds to option c.
