A charge of 90 C passes through a wire in 1 hour 15 minutes. What is the current in the wire?

We calculate current from the formula: I = t q ​ , where q is a electric charge transferred over time t Time should be converted to seconds: 1h 15 min= 75min= 4500s I= 4500 s 90 C ​ = 0 , 02 A Result is in unit-Ampere

Current = C / seconds.
1 hour = 3600 seconds 15 minutes = 900 seconds
1 hour 15 minutes = 4500 seconds
90 C / 4500 sec = 0.02 amperes = 20 milliamperes

The current in the wire is calculated using the formula I = t q ​ . By converting 1 hour and 15 minutes to seconds, we find the time to be 4500 seconds. Thus, the current is 0.02 Amperes (A).
