Pure R, L and C Circuits

The reactance of capacitor at 50 Hz50\text{ Hz} is 5 Ω5\ \Omega. If the frequency is increased to 100 Hz100\text{ Hz}, the new reactance is

Show answer and solution

Answer: (c)

  1. XC∝1fX_C \propto \frac{1}{f}
  2. XC′=5×50100=2.5 ΩX_C' = 5 \times \frac{50}{100} = 2.5\ \Omega
  3. So the answer is (c) 2.5 Ω2.5\ \Omega.
