A $20\Omega$ resistor, $1.5$ H inductor and $35\mu F$ capacitors are connected in series with $200$ V, $50$ Hz ac supply. Calculate the impedance of the circuit and also find the current through the circuit?

Impedence equal to resistance
$z=R\quad \phi ={ 0 }^{ o }$
$z=20\Omega$
${ I }_{ v }=\dfrac { { E }_{ v } }{ Z } =\dfrac { 200 }{ 20 } =10A$
Average power transferred
$P={ E }_{ v }{ I }_{ v }\cos { { \theta }^{ o } }$
$200\times 20\times 1$
$=200watt$
