In a linear circuit consisting of

*R*= 9Î© and*L*= 8mH, a current, A is flowing. Find the equation of applied voltage.Solution

Here,

For DC component
Current,
âˆ´

For first harmonic component
Current, A
Impedance,
âˆ´

For third harmonic component
Current, A
Impedance,
âˆ´
âˆ´ applied voltage is given as,

*R*= 9 Î© and*L*= 8 mH, AFor DC component

*I*_{0}= 5A,*Z*_{0 }=*R*= 9Î©*V*_{0}=*I*_{0}Ã— R = 5Ã—9 = 45*V*For first harmonic component

For third harmonic component
