An L – C – R circuit of R=100 Ω is connected to an AC source 100 V, 50 Hz. The magnitude of phase difference between current and voltage is 30°. The power dissipated in the L – C – R circuit is
View answer and explanation
Correct option: B
86.6 W
Option B (86.6 W) is correct because the power dissipated is calculated using the formula P = Vrms * Irms * cos(phi), where cos(phi) is the power factor.
