Get XL by 2pieFL = 50π
str 50π to A.
then get V = 30(1-e^-A/60),
V = 27.81 its near 27.33.

The voltage across an inductor is Ve^-tR/L and this formula we get 2.72 V, and the rest will appear across the resistance i.e. 27.

Since the frequency of the input is low the reactance of the inductor will be low. so the R>X and hence we will get max voltage across resistance.

The exact value of voltage i can't say as something is wrong with question ;)

T = 1/F.

Er = E(1-e^(-R/L)(1/F0)).

Er = 30(1-e^(-60/200m)(1/125).

Er = 27.28V.

@Brad.

It is the voltage across the inductor but here it is asked to.

Find out output voltage i.e, voltage across resistor.

I think answer should be 2.67v.

Vl = v*e^-(R/L)t.
v - Applied voltage.
Vl - Voltage drop across inductor during transient.

Ya but in case of rl circuit.

v = vm*e^-(R/L)T is there, but through this we can't get desire answer which is in option.

From the rule, we can get the voltage across inductance, so when we subtract the inductance voltage from input voltage we can get the right answer.
