Lcr Circuit Phase Diagram. An lcr circuit also known as a resonant circuit tuned circuit or an rlc circuit is an electrical circuit consisting of an inductor l capacitor c and resistor r connected in series or parallel. Fig 9 1 4 illustrates the phasor diagram for a lcr series circuit in which x c is greater than x l showing that when v c exceeds v l the situation illustrated in fig 9 1 3 is reversed.
It fulfills along with their properties like reactance impedance and phase. An lcr circuit also known as a resonant circuit tuned circuit or an rlc circuit is an electrical circuit consisting of an inductor l capacitor c and resistor r connected in series or parallel. The voltage across the resistor v r is in phase with the current and is shown in green.
The phasor diagram for a series rlc circuit is produced by combining together the three individual phasors above and adding these voltages vectorially.
When an ac source of emf e e 0 sin 1 0 0 t is connected across a circuit the phase difference between the emf e and the current i in the circuit is observed to be π 4 as shown in the diagram. The phase angle θ now shows that the circuit current i s leads supply voltage v s by. The blue vector shows v l at 90 while the gold vector represents v c at 90. This is shown in red in the diagram.
