Current passing through a wire decreases...

Current passing through a wire decreases linearly from `10 A` to `0` in 4s. Find total charge flowing through the wire in the given time interval.

Text Solution

Verified by Experts

Current versus time graph is as shown in figure
Area under thlis graph will gave us net charge flow.
Hence, `/_\q=Area`
`=1/2xx "base" xx "height"`
`=1/2x4xx10`
`=20C`
