My first answer is also zero, but if you follow the principle behind resistance in series connection, V1=V2=V3=Vn, so 6v=voltage in resistor=voltage in inductor.

At t=0s ; f is infinite , and XL = 2pfL, hence XL is infinite.
Means open circuit.
Hence, the total voltage will be across an inductor and hence 6v.

For dc inductor acts as a short cicuit. So voltage across inductor is zero.
Then how the voltage across inductor is 6v?
Then how the voltage across inductor is 6v?

The inductor property is opposes to sudden changing current does not opposes voltage so total voltage appear across it.

The Answer is 6v as there is no back EMF produced by the current in the inductor when we just close the switch.

Voltage drop = 0.
In DC network inductor works as short path. So no drop here.
The final answer is 0.0V.

IN SERIES RL CIRCUIT Vs=VL x (e^-t/time constant).
If t=0 ; Vs= VL x e^0.
Therefore Vs=VL = 6V in t=0.
If t=0 ; Vs= VL x e^0.
Therefore Vs=VL = 6V in t=0.

Current is given by i = I(1-e^Rt/L),
When t=0, i= 0,
Emf = L*di/dt.
So voltage is zero. Answer is A.
When t=0, i= 0,
Emf = L*di/dt.
So voltage is zero. Answer is A.

As inductor doesnt allows sudden change in current. The voltage drop will be the same 6V.

An inductor is does not allow sudden change in only current so voltage is supply voltage.
