Capacitance Flashcards
is a passive element designed to store energy in its electric field.
capacitor
Formula of capacitor when voltage is applied
q = Cv
unit of capacitance
farad (F)
is the ratio of the charge on one plate of a capacitor to the voltage difference between the two plates
Capacitance
Formula of capacitance
C = ϵA/d
Formula for the current-voltage relationship of the capacitor
i = C (dv/dt)
Formula for the instantaneous power delivered to the capacitor
p = vi = Cv (dv/dt)
Formula for the voltage-current relation of the capacitor
v(t) = 1/C ∫ i(T)dT+v(t0)
lower limit and upper limit of t
energy stored in the electric field that exists between the plates of the capacitor
w = 1/2 (Cv^2) or w = (q^2) / 2C
