Difficulty: EasyCapacitors

Match each capacitor term or specification on the left with its correct electrical description on the right.

  • Farad (F)The standard unit used to quantify electrical capacitance
  • DielectricThe insulating material separating the conductive plates
  • Electrolytic capacitorA polarized capacitor type sensitive to connection polarity
  • Working voltage ratingThe maximum continuous voltage that can safely be applied

Answer

Farad (F) matches with the standard unit used to quantify electrical capacitance; Dielectric matches with the insulating material separating the conductive plates; Electrolytic capacitor matches with a polarized capacitor type sensitive to connection polarity; Working voltage rating matches with the maximum continuous voltage that can safely be applied.
Each term accurately pairs with its foundational physical definition: the farad is the SI unit of capacitance, the dielectric is the insulating medium between plates, electrolytic capacitors are polarized devices requiring correct terminal orientation, and the working voltage rating defines the maximum safe operating voltage before dielectric puncture.

Step-by-Step Solution

1
Identify the standard unit of capacitance
Farad (F) is the metric unit measuring charge storage ability.
Capacitance (C=Q/VC = Q/V) is quantified in units of farads.
2
Identify the insulating component inside a capacitor
The dielectric is the insulating layer.
Dielectrics block steady direct current conduction across the plates while concentrating the electric field.
3
Identify the polarized capacitor category
Electrolytic capacitors have designated positive and negative terminals.
Reverse polarization disrupts the chemical oxide layer, potentially destroying the component.
4
Identify the safe maximum voltage parameter
Working voltage rating represents the dielectric breakdown threshold.
Operating above this threshold risks arcing and dielectric breakdown.
