A charge of 90 C passes through a wire for 30 seconds. Then the current in the wire will be _____?
Answer: 3 A
Explanation
Current (I) is defined as the rate of flow of charge (Q) with respect to time (t). The formula to calculate current is:
I = Q / t
Given:
Q = 90 C (charge)
t = 30 s (time)
I = 90 C / 30 s = 3 A
So, the current in the wire is 3 A.
