Question

A bolt of lightning discharges 9.7 C in 8.9 x 10^-5 s. What is the average current during the discharge?

Answer 1

Answer:
`1.089* 10^5\ A`

Step-by-step explanation:

Given

Charge discharged
`Q=9.7\C`

time taken
`t=8.9* 10^(-5)\ s`

Current is given as rate of change of discharge i.e.

`\Rightarrow I=(Q)/(t)\\\\\Rightarrow I=(9.7)/(8.9* 10^(-5))\\\\\Rightarrow I=1.089* 10^5\ A`

Therefore, the average current is
`1.089* 10^5\ A`
