Question
Calculate the amount of charge that would flow in 2h through an element of an electric bulb drawing a current of 0.25 A.
Answer
Given that the current I = 0.25 A and the time t = 2 h = 7200 s (since 1 hour = 3600 seconds), we can substitute these values into the formula to get:
Q = It = 0.25 A × 7200 s = 1800 C
Therefore, the amount of charge that would flow in 2 hours through an element of an electric bulb drawing a current of 0.25 A is 1800 coulombs.
