Question

The energy dissipated in the L.C.R circuit in :

• A. R only
• B. L only
• C. C only
• D. All the above option.

Answer 1

The correct option is A

R only

L.C.R Circuit:

1. Because the phase difference between current and voltage in the case of a resistor is zero, energy dissipates only through resistance in an L.C.R circuit.
2. An L.C.R circuit, also known as a resonant circuit, tuned circuit, or R.L.C circuit, is a series or parallel connection of an inductor (L), capacitor (C), and resistor (R).
3. In terms of the phasor, the L.C.R circuit analysis can be better understood. A phasor is a quantity that rotates.
