Question

For a series LCR circuit with \[C=796\,\mu\mathrm{F}\] and frequency \[50\,\mathrm{Hz}\], what is the capacitive reactance?

Options

• \[X_C=4\,\Omega\]

• \[X_C=5\,\Omega\]

• \[X_C=3\,\Omega\]

• \[X_C=8\,\Omega\]

Answer 1

Capacitive reactance is \[X_C=1/(2\pi\nu C)\]. With the stated capacitance and frequency, it is approximately \[4\,\Omega\].
