Answer:
Inductive reactance is 125.7 Ω
Explanation:
It is given that,
Inductance, 
Voltage source, V = 15 volt
Frequency, f = 400 Hz
The inductive reactance of the circuit is equivalent to the impedance. It opposes the flow of electric current throughout the circuit. It is given by :




So, the inductive reactance is 125.7 Ω. Hence, this is the required solution.
 
        
             
        
        
        
Frequency= velocity of light/wave length
 Fr= 3×10^8/510×10^-9
 Frequwency=5.88×10^14 Hz
