Question

The electric potential energy stored in the capacitor of a defibrillator is 73 j, and the capacitance is 120 f. what is the potential difference that exists across the capacitor plates?

Answer 1

The relationship between electrical potential energy (PE), capacitance (C), and potential difference (V) can be expressed through the equation,

                                  V  = PE / C

V is equal to the quotient of potential energy and capacitance.

 

When we substitute the known values from the item,

                               V =  73 J/ 120 C

                                    V = 0.61 J/C

Thus, the voltage or potential difference is equal to 0.61 V.
