Question

A capacitor is connected across an ac generator whose frequency is \( 910 \mathrm{~Hz} \) and whose peak out put voltage is \( 130 \mathrm{~V} \). The rms current in the circuit is \( 2.3 \mathrm{~A}

Answer 1

In this circuit, a capacitor is connected across an AC generator with a frequency of 910 Hz and a peak output voltage of 130 V. The rms current in the circuit is 2.3 A.

Step-by-step explanation:

In this circuit, a capacitor is connected across an AC generator. The AC generator has a frequency of 910 Hz and a peak output voltage of 130 V. The rms current in the circuit is 2.3 A.

For an AC circuit with a capacitor, the current leads the voltage by a phase angle of 90 degrees. The reactance of a capacitor in an AC circuit is given by:

Xc = 1 / (2 π f C)

Where Xc is the capacitive reactance, f is the frequency of the AC generator, and C is the capacitance of the capacitor.
