The current through a wire depends on time as `i=(2+3t)A`. Calculate the charge crossed through a cross section of the wire in 10sec.

Text Solution

Verified by Experts

`i=(dq)/(dt)rArrdq=(2+3t)dt`
`int_(0)^(q)dq=int_(0)^(10)(2+3t)dtrArrq=(2t+(3t^(2))/(2))_(0)^(10)`
`q=2xx10 +(3)/(2)xx100=20+150=170C`
