Physics - EMI/AC Question with Solution | TestHub

Given that

$C=30 \mathrm{\mu F}=30\times {10}^{-6}\mathrm{ F}$

$V=150\mathrm{ V}, f=\mathrm{60 }\mathrm{Hz}$

$I_{\mathrm{r}\mathrm{m}\mathrm{s}}=\frac{V}{X_C}=\frac{150}{\frac{1}{\omega C}}$

$=150\times \omega C$

$=150\times 2\pi f\times C$

$=150\times 2\times 3.14\times 60\times 30\times {10}^{-6}$

$=1.6956\mathrm{ A}\simeq 1.7\mathrm{ A}$
