Answer:
Frequency required will be 2421.127 kHz
Explanation:
We have given inductance [tex]L=0.450H=0.45\times 10^{-3}H[/tex]
Current in the inductor [tex]i=1.90mA=1.90\times 10^{-3}A[/tex]
Voltage v = 13 volt
Inductive reactance of the circuit [tex]X_l=\frac{v}{i}[/tex]
[tex]X_l=\frac{13}{1.9\times 10^{-3}}=6842.10ohm[/tex]
We know that
[tex]X_l=\omega L=2\pi fL[/tex]
[tex]2\times 3.14\times f\times 0.45\times 10^{-3}=6842.10[/tex]
f = 2421.127 kHz
