Phasor diagram & energy OF SHM

With the help of a phasor diagram find an expression for impedance (Z) in a series L-C-R circuit.

What is a phasor diagram ? Draw a phasor diagram when a pure resistor is conneted acorss an a.c. supply and show that current and voltage are in the same phase.

What are the SI units of reactance and impedance in a.c. circuit ?

Time Period || Phasor Diagram

Use a phasor diagram to represent the sine waves in the following Figure.

Draw the phasor diagram of a series LCR connected across an ac source V= V_(0) sin omegat . Hence derive the expression for the impedance of the circuit . Obtain the conditions for the phase angle under which the current is (i) maximum and (ii) minimum.
