Circuit analysis (Question 1 (20 Marks)) — UPSC Physics Optional CSE 1999 Paper I

An L–C–R circuit has a resistance of 100 ohms, a capacitance of 0.2 \mu\text{F} and an inductance of 5 H. An ac source E = 50 \sin (1000 t)\text{ volt} is connected in the circuit. Calculate the average power dissipated.
