Imagine simple RL circuit connected to a battery source. Lets assume that we are decreasing the resistor value linearly in a constant steady rate. This will make the current being increased linearly. Thus the current will be increasing in an inductor and it will cause a voltage to build up across the inductor which will oppose a further change in current. But will this voltage across the inductor decrease the current in a circuit? Why the current will still be inreasing in the same constant steady rate while the resulting voltage in a circuit has been changed. Why the voltage which builds up doesn't change the current? Or may be it actually changes the current which changes the voltage again and so on and we dont see these fluctuations?
