A charge of 90 C passes through a wire for 30 seconds. Then the current in the wire will be _____?

3 mA

3 A

0.3 mA

0.3 A

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.
