In an AC-circuit, the power or rate of energy dissipated is
P=VI‌cos‌φ
where, φ= phase difference between voltage and current.
For inductor (L) and capacitor (C), the phase difference between V and I is 90∘.
For resistor (R), the phase difference between V and I is zero.
Hence, only due to resistor R, energy is dissipated in an L−C⋅R circuit.
