Capacitance Flashcards
A dielectric is a circuit component that temporarily stores charges within the circuit.
False. Capacitor.
This separates the two conducting plates of a capacitor.
Dielectric.
A dielectric __ and ___ electric current.
impedes, stores
Capacitance is…
The amount of charges stored in a capacitor per unit of electric potential.
What is the equation for capacitance?
C = Q/V
C - capacitance
Q - magnitude of charge on each plate
V - voltage applied to each plate
