If the resistance of the coil is 10 π^2Ω, the total charge flowing through the coil during this time is.

A long solenoid of diameter 0.1 m has 2×10^4 turns per metre.At the centre of the solenoid, a coil of 100 turns and radius 0.01 m is placed with its axis coinciding with the solenoid axis.The current in the solenoid reduces at a constant rate to 0 A from 4 A in 0.05 s. If the resistance of the coil is 10 π^2Ω, the total charge flowing through the coil during this time is.

A coil of resistance 400 Ω is placed in a magnetic field. If the magnetic flux ϕ (Wb) linked with the coil varies with time t (sec) as ϕ = 50t2 +4 The current in the coil at t= 2 sec is A long solenoid of diameter 0.1 m has 2×10^4 turns per metre.At the centre of the solenoid
