V of 200,000,000 and consists of a current of 1,000A that flows for a fraction of a second.Calculate thepower

Answer 1

The formula for calculating power is: P = I E, where P is the power, I is the current and E is electrimotive force (voltage). The solution to your problem would be: P = 1000 x 200,000,000, therefore the power would be 200,000,000,000 watts or 200,000 megawatts.

Answer 2

Power and current are rates per unit time, so it doesn't matter whether it's a fraction of a second or a year, the power will be the same. The power is just voltage times current, or 200,000,000 V x 1,000 A = 200,000,000,000 W or 200 gigawatts.
