A capacitor of capacitance 102/π µF is connected across a 220 V, 50 Hz A. C. mains. Calculate the capacitive reactance, RMS value of current and write down the equations of voltage and current.

The capacitive reactance will be "100Ω" and RMS value of current is "2.2 A". A further explanation is provided below.

Explanation:

Given:

Now,

The capacitive reactance will be:

⇒

RMS value of current will be:

⇒

So that,

⇒

⇒

hence,

The equation will be:

⇒

and,

⇒
