In typical lightning, there is 109 J energy transfer across the potential difference of 5 × 107 V during a time interval of 0.2 s. What is the total amount of charge transferred between cloud and ground?
Answer & explanation
Correct answer: option 3
U = q x V
Q = U/V
Q = \(\frac{10^{9}}{5 * 10^{7}}\) = 20 C
