Question

Calculate the resistance and inductance given a frequency of 50hz, applied voltage of 240v, capacitance of 40*10^-6f and current of 1.5<-35

Answer 1

$Resistance, R=V/A=240/1.5=160\Omega$

calculate inductance L

at resonance $X_L=X_C=R$

So $X_L=2\pi fL$

$R=2\pi fL$

$L=\frac{R}{2\pi f}=\frac{160}{2\times \pi \times 50}=0.5093H$
