What is the average power dissipated in original LCR circuit? An LCR series circuit with a resistance of 100 Ω is connected to an AC source of 200 V (rms) and angular frequency 300 rad/s. When only the capacitor is removed, the current lags behind the voltage by 60o. When only the inductor is removed the current leads the voltage by 60o.



A. 50 W
B. 100 W
C. 200 W
D. 400 W

The correct answer to this question is D, 400 W. RCL circuits consist of three parts of the electrical circuit. Each letter stands for a part of the circuit and has its own meaning. The first is the R, which is the resistor.

Its purpose is to resist the passage of the current. Second is the L, which stands for the inductor. It stores energy that allows the current to flow through. The C is the capacitor, which also stores energy, but does so in a field. Together, they are connected in a series or in parallel. Each circuit has its own power that can be dissipated.

An RLC circuit is one in which consists of three main parts of an electrical circuit. These three things each being with one of the three letters in the title of this circuit except for one. The R stands for the resistor. The L stands for the inductor. The C stands for the capacitor. These are connected in a series or parallel.

There is an average power that can be dissipated in the original LCR circuit. This can be found out if certain information is given. In this case, the LCR series circuit with a resistance of 100 ohms is connected to an AC source of 200 V or rms and angular frequency 300 rad/s. There will be 400 w if the inductor is removed from the current leads the voltage by 60 ohms.
