Answer» Charge through a cross section of a conductar is given by θ = 5t2 - 3 t coulomb. The average currenl through the conductar in the interval t1 = 2s to t2 = 45. change at the given instants θ = 5t2 - 3t At t1 = 25 θ1 = 5(2)2 - 6 = 14 c At t2 = 45 θ2 = 5 (4)2 - 12 θ2 = 68 c Average current I \(=\frac{Δ\theta}{Δt}\) \(=\frac{68-14}{4-2}\) \(=\frac{54}{2}\) I = 27 ampere |
