Question 299: AC fundamentals

Question

In an a.c. circuit, the reactance of a coil is $\sqrt{3}$ times its resistance. The phase difference between the voltage across the coil to the current through the coil will be

Accepted Answer

$$\begin{aligned}
& 	an \phi=\frac{\mathrm{x}_{\mathrm{L}}}{\mathrm{R}} \
	herefore\quad& 	an \phi=\frac{\sqrt{3} \mathrm{R}}{\mathrm{R}}=\sqrt{3} \
& 	herefore\quad \phi=	an ^{-1}(\sqrt{3})
\end{aligned}$$

Answer

$	an ^{-1}(0)$

Answer

$	an ^{-1} \frac{1}{\sqrt{3}}$

Answer

$	an ^{-1}(1)$

Answer

$	an ^{-1}(\sqrt{3})$
