When we have a DC voltage source with a switch in series with $RL$ and the switch is closed at $t=0$ then it is said that current is zero initially, but the voltage across inductor is same as that of applied voltage (according to Kirchhoff voltage law) so there should be current (according to $V=L(di/dt)$) but it contradicts the initial statement so how do I understand this?
If we have only inductor I understand that current increases linearly with time but addition of resistor makes the current increase exponential, how to understand this intuitively (I understand from the equations but not theoretically (intuitively) how it is happening)?
I understand that changing current causes the induced EMF which opposes the changing current, but what I don't understand is - won't it cause the current to be constant but here it seems to contradict that changing current should be there for EMF to exist, so how do we explain that voltage is reducing to zero and current is increasing with respect to the confusion I mentioned above in inductor of $RL$ circuit (so basically I am not understanding the behavior of induced EMF in inductor)? Please provide an intuitive explanation.
I have gone through lot of questions on this site but couldn't find any answers regarding my confusion, I am stuck with this. Please help me with this.
