In the figure shown a conducting rod of length `l`, resistnace `R` and mass `m` is moved with a constant velocity `v`.The magnetic field `B` varies with time `t` as `B=5 t`, where `t` is time in second.At `t=0` the area of the loop containing capacitor and the rod is zero and the capacitor is uncharged.The rod started moving at `t=0` on the fixed smooth conducting rails which have negligible resistance.Find (i)The current in the circuit as a function of time `t`.
(ii)If the above system is kept in vertical plane such that the rod can move vertically downward due of gravity and other parts are kept fixed and `B`=constant =`B_(0)`.then find the maximum current in the circuit.
