Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 2):(6.5 A)
Concept:
The reactance of a capacitor is given by:
XC =
where
XC = reactance
f = supply frequency
C = capacitance
R.M.S. value of capacitor current is given by:
Calculation:
Given
C = 90 μF
f = 50 Hz
Vrms = 230 V
XC =
=
= 35.36 Ω
=
= 6.5 A
