The leakage resistance of a capacitor appears in an equivalent circuit as

  • A.a second capacitance in parallel with the first
  • B.a resistance in parallel with the capacitance
  • C.a resistance in series with the capacitance
  • D.an inductance in series with the capacitance

Answer: B

Leakage is a conduction path through the dielectric, so it lies across the plates and slowly discharges a charged capacitor. The series resistance in the same equivalent circuit represents the resistance of the plates and leads together with the dielectric loss.
