Show that Equation for the phase angleof a series circuit gives the correct result for a capacitor-only circuit.
The expression for phase angle of series circuit gives correct result for capacitor only circuit.
We are given that the Equation which is .
We need to prove that this equation for phase angle of series circuit gives correct result for capacitor only circuit.
We know equation,
Here gets canceled so equation can be rewritten as :
We are also given that ,
From here phase angle becomes
Similarly for Inductor circuit conditions are
Hence proved that it gives correct result for capacitor only circuit.
The telecommunication circuit shown in has a parallel inductor and capacitor in series with a resistor.
a. Use a phasor diagram to show that the peak current through the resistor is
Hint: Start with the inductor phasor .
b. What is in the limits and ?
c. What is the resonance frequency ? What is at this frequency?
