Complete Question:

Find the capacitive reactance of a 0.1 microfarad capacitor with frequency 50Hz and at 200Hz​.

Answer:

I. Capacitive reactance = 31826.86 Ohms.

II. Capacitive reactance = 7956.72 Ohms.

Step-by-step explanation:

Given the following data;

Capacitance = 0.1 uF = 0.0000001 Farad

Frequency = 50 Hz and 200 Hz

To find the capacitive reactance;

Mathematically, the capacitive reactance of an electronic circuit is given by the formula;


X_(c) = \frac {1}{2 \pi fc}

Where;

  • Xc is capacitive reactance.
  • f is the frequency.
  • c is the capacitance.

Substituting into the formula, we have;

I. At frequency, f = 50 Hz


X_(c) = \frac {1}{2 * 3.142 * 50 * 0.0000001}


X_(c) = \frac {1}{314.2 * 0.0000001}


X_(c) = \frac {1}{0.00003142}


X_(c) = 31826.86

II. At frequency, f = 200 Hz


X_(c) = \frac {1}{2 * 3.142 * 200 * 0.0000001}


X_(c) = \frac {1}{1256.8 * 0.0000001}


X_(c) = \frac {1}{0.00012568}


X_(c) = 7956.72
