Question

A cloud is at a potential of $8\times {10}^6$ volts relative to the ground. A charge of 80 coulombs is transferred in lighting stroke between the cloud and the ground. Assuming the potential of the cloud to remain constant the energy dissipated is _.

• A. $6.4\times {10}^{8}joules$
• B. $6.4\times {10}^{5}joules$
• C. ${10}^{5}joules$
• D. ${10}^{7}joules$

Answer 1

The correct option is A $6.4\times {10}^{8}joules$

Energy Dissipated =$QV=80\times 8\times {10}^6=6.4\times {10}^{8}joules$
