A silver wire 1mm diameter carries a charge of 90 coulombs in 1 hours and 15 minutes. Silver contains `5.8xx10^(28)` free electrons per `cm^(3)` find the current in wire and drift velocity of the electron.

Explanation

To solve the problem step by step, we will first calculate the current in the silver wire and then find the drift velocity of the electrons.

### Step 1: Calculate the time in seconds
The total time given is 1 hour and 15 minutes. We need to convert this into seconds.

1 hour = 60 minutes
1 hour and 15 minutes = 60 + 15 = 75 minutes
