Lcr Circuit. Therefore it will be easier to consider that the voltage v r is the voltage across the total circuit resistance which comprises the internal resistance of l added to any separate fixed resistor. An rlc circuit is an electrical circuit consisting of a resistor r an inductor l and a capacitor c connected in series or in parallel.
Phasor diagram of parallel rlc circuit i r is the current flowing in the resistor r in amps. Lcr circuits are also useful to change the impedance of the circuit to increase or decrease the resistance to the current of different frequencies. Make sure that you set the lcr meter to 10khz.
In the parallel rlc circuit all the components are connected in parallel.
Then setup a rl high pass circuit using a value of r that gives a circuit rolloff frequency of approximately 10khz. Then setup a rl high pass circuit using a value of r that gives a circuit rolloff frequency of approximately 10khz. I l is the current flowing in the inductor l in amps. Series lcr circuit has applications in radio and communication engineering.
