given the following L-R circuit...

A battery of emf E is connected in series with a resistance R and inductor coil with inductance L...

now if i current flows through it then using kirchoff's law

E - iR - L(di/dt) = 0

and also gien di/dt = 5 A/s

question if we solve the eqn we'll always find the value of i to be same....however we are given di/dt=5A/s...

i.e the current is increasing at 5 A per second....

but the above equation gives constant value of i....

justify...........

ratings ensured........... ( mail me to know the answer)...
