Question

The rms value of the phasor current I in the circuit shown (in amperes) is

• A. 1

Answer 1

The correct option is A 1

R = 100 $\Omega$

$X_L=\omega L=100\Omega$

$X_c=\frac{1}{\omega C}=100\Omega$

Z = 100 + j(100 - 100)

$\left|Z\right|=100\Omega$

$I=\frac{V_{rms}}{z}=\frac{(\sqrt{2}\times 100)/\sqrt{2}}{100}\Rightarrow 1A$
