Phasor Diagram Of Series Rlc Circuit At Resonance. Impedance triangle of rlc series circuit. A series rlc circuit consists of a resistor r 20 ohm inductor l 0 5 h and capacitor c 0 5 uf.
X l 2πfl and x c 1 2πfc. Current i lags behind the applied voltage v by 0 as shown in phasor diagram of figure 2 c. A sinusoidal voltage of rms value 20 volts at the frequency of response is applied across the circuit.
Resonance in series rlc circuit.
The voltage drop across the inductive reactance will be perpendicularly upward. This demonstration shows a phasor diagram in an ac series rlc circuit. When the ac voltage is applied through the rlc series circuit the resulting current i flows through the circuit and thus the voltage across each element will be. The current in an rlc series circuit is determined by the differential equation.
