A capacitor of capacitance 0.5 `muF` is connected to a source of alternating e.m.f. of frequency 100 Hz. What is the capacitive reactance? `(pi=3.142)`

Answer» Given, `C=0.5mu F=0.5xx10^(-6)F=5xx10^(-7)F, f=100Hz, pi=3.142`
Capacitive reactance, `X_(c)=(1)/(2pi fC)`
`=(1)/(2xx3.142xx100xx5xx10^(-7))`
`=3182.66Omega ~~3.182k Omega`
