Questions & Step-by-Step Solutions

What is the impedance of a capacitor at a frequency of 60Hz with a capacitance of 10μF?
  • Step 1: Understand that impedance (Z) of a capacitor is calculated using the formula Z = 1 / (jωC).
  • Step 2: Identify the frequency (f) given in the question, which is 60Hz.
  • Step 3: Convert the frequency to angular frequency (ω) using the formula ω = 2πf. So, ω = 2π * 60.
  • Step 4: Calculate ω: ω = 2 * 3.14 * 60 ≈ 376.99 rad/s.
  • Step 5: Identify the capacitance (C) given in the question, which is 10μF (microfarads). Convert this to farads: C = 10 * 10^-6 F = 10e-6 F.
  • Step 6: Substitute ω and C into the impedance formula: Z = 1 / (j * 376.99 * 10e-6).
  • Step 7: Calculate the denominator: j * 376.99 * 10e-6 ≈ j * 0.00037699.
  • Step 8: Now calculate Z: Z = 1 / (j * 0.00037699).
  • Step 9: The magnitude of Z is approximately 2652Ω.
