Question

An ac source of voltage V Vo sinct is connected to a series combination of L, C and R. Use the
* phasor dingrum to obtain the expression for the impedance of the circuit and phase angle between
voltage and current. Find the condition when current will be in phase with voltage. What is the
circuit in this condition called?​

Answer 1

Answer:

Impedance(Z)=

$\sqrt{ {r }^{2} + {(xl - xc)}^{2} }$
