What is the energy stored in the 10.5 μ F 10.5 μF capacitor of a heart defibrillator charged to 8250 V?

356.33 J

Explanation:

Energy: This can be defined as the ability or the capacity to do work. The S. I unit of Energy is Joules (J).

The Energy stored in a capacitor = 1/2CV²

E = 1/2CV² ... Equation 1.

Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = potential difference across the plates of the capacitor.

Given: C = 10.5 μF = 10.5*10⁻⁶ F, V = 8250 V.

Substitute into equation 1

E = 1/2 (10.5*10⁻⁶) (8250) ²

E = 357.33 J.

Thus the energy stored in the defibrillator = 356.33 J
