In an $AC$ circuit an alternating voltage $e = 2002 sin 100 t$ volt is connected to a capacitor of capacity $1 μ F$ . The rms value of the current in the circuit isNEET 2011 (Screening)

Options:

Answer:

Solution:

Given, $e = 2002 sin 100 t$ and $C E_{rms} X_{C} i_{rms} i_{rms} = 1 μ F = 200 V = \frac{1}{ω C} = \frac{1}{1 \times 1 0 ^{- 6} \times 100} = 1 0^{4} Ω = \frac{E _{rms}}{X _{C}} = \frac{200}{1 0 ^{4}} = 2 \times 1 0^{- 2} A = 20 mA$
