The potential difference between a cloud and the ground is 4 MV. A charge of 200 C is transferred in a lightning stroke between the cloud and the ground. How much energy is dissipated?
To determine: The amount of energy dissipated between the cloud and the ground.
Answer:
The amount of energy dissipated between the cloud and the ground is 8 × 108 J
Given data:
V is 4 MV.
Q is 200 C
Formula used:
Consider the expression for stored energy (W).
W = QV (1)
Here,
Q is the charge, and
V is the voltage.
Explanation:
Substitute 200 C for Q and 4 MV for V in equation (1)
Conclusion:
Thus, the amount of energy dissipated between the cloud and the ground is 8 × 108 J
