A 5 cm long solenoid having \[10\,\,\Omega \] resistance and 5 mH inductance is joined to a 10 V battery, At steady state, the current through the solenoid (in ampere) will be
A) 5
B) 2
C) 1
D) zero
Correct Answer:
C
Solution :
At steady state, the current through the solenoid \[i=\frac{E}{R}=\frac{10}{10}=1.A\]
