What is the capacitive reactance of a capacitor of 10μF at a frequency of 60 Hz? (2016)
  • Step 1: Identify the formula for capacitive reactance, which is Xc = 1 / (2πfC).
  • Step 2: Identify the values needed for the formula: frequency (f) = 60 Hz and capacitance (C) = 10μF (which is 10e-6 F).
  • Step 3: Substitute the values into the formula: Xc = 1 / (2π * 60 * 10e-6).
  • Step 4: Calculate the denominator: 2π * 60 * 10e-6 = 0.00003769911184307752.
  • Step 5: Calculate the capacitive reactance: Xc = 1 / 0.00003769911184307752 = 265.26Ω.
