An alternating emf $E = 1102 sin 100 t$ volt is applied to a capacitor of $2 μ F$ , the rms value of current in the circuit is _____ $mA$ ,

Answer:

22.00

Solution:

$C X_{C} = i_{o} i_{rms} = 2 μ f; E = 1102 sin (100 t) = \frac{1}{ω c} = \frac{1}{100 \times 2 \times 1 0 ^{- 6}} \frac{10000}{2} = 5000Ω = \frac{110 2}{5000} = \frac{110 2}{5000 2} = \frac{110}{5} mA = 22 mA$
