Question

Draw phasor diagrams for the following circuits.

A) For the first circuit: Analyze a series RC circuit. So an emf with frequency w and peak voltage V connected in series to a resistance with peak voltage V_R and a capacitor with a peak votage V_C.

B) For the second one, do a parallel RL circuit. Same emf as above, but resistance R in parallel to inductor with inductance L.

Step by step

Thank you

Answer 1

A) The series RC circuit is shown below-

Using KVL, the phasor equations can be written as-

Taking, as reference, the phasor diagram can be drawn as-

For Voltage part-

For Impedance part-

B)  The parallel RL circuit is shown below-

Using KVL, the phasor equations can be written as-

(in terms of admitance)

Taking, as reference, the phasor diagram can be drawn as-

For current-

For Admitance-
