Question

What is the potential difference across a refrigerator when 75 C of charge transfer 9.0 x 10^7 J of energy to the compressor motor?

A) 0.12 V
B) 1.2 V
C) 120 V
D) 12 V

Answer 1

The potential difference across the refrigerator is 1.2 V.

Step-by-step explanation:

The potential difference (V) across a refrigerator can be calculated using the formula:

V = E/Q

where E = energy transferred and Q = charge transferred.

In this case, the energy transferred (E) is given as 9.0 x 10^7 J and the charge transferred (Q) is given as 75 C. Plugging these values into the formula, we get:

V = (9.0 x 10^7 J) / (75 C) = 1.2 x 10^6 V = 1.2 V

Therefore, the potential difference across the refrigerator is 1.2 V.
