Answer:A
Explanation:
In R-L circuit current is given by
![i=i_0\left [ 1-e^{\frac{-t}{L/R}}\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-e%5E%7B%5Cfrac%7B-t%7D%7BL%2FR%7D%7D%5Cright%20%5D)
where i=current at any time t

R=resistance
L=Inductance
at t=0
approaches to 1
therefore ![i=i_0\left [ 1-1\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-1%5Cright%20%5D)
i=0
when t approaches to
,
approaches to zero
thus 
thus we can say that initially circuit act as broken wire with zero current
and it increases exponentially with time and act as ordinary connecting wire
the resistance is 80.8Ω and average power 178.2 W
a) the value of resistance is given as,
R=rms voltage / rms current
and rms current = 2.1/√2
= I°/√2
rms current = 2.1/√2
rms current = 1.48
therefore R = 120/1.48
=80.4Ω
b) average power is product of rms current and rms voltage
P=120× 1.48
=178.2 W
