To ignite the flash lamp when photographing, a capacitor with a capacity of 1000 μF, charged

To ignite the flash lamp when photographing, a capacitor with a capacity of 1000 μF, charged to a voltage of 200V, is used. Calculate the energy of the electric field of the condenser released when the lamp flickers.

The energy stored by the capacitor is determined by the formula:
W = CU ^ 2/2;
In a specific case, we have:
W = 1000 * 10 ^ -6 * (200) ^ 2/2 = 1000 * 10 ^ -6 * 4 * 10,000 / 2 = 20,000,000 * 10 ^ -6 = 20 J.
Please note that the capacitance value given in μF should be converted to farads.
