As you would expect, the potential difference across capacitors connected in parallel is the same individually as the potential at the junction.
Δv = Δv₁ = Δv₂ = Δv₃ ....... =Δvₙ
However, contrary to capacitors connected in series, the charge on each capacitor is different. Using our earlier capacitance equation, we find the following.
Qtotal = ∑iQi = ∑iciΔvi
Since the potential differences are all equal, for capacitors connected in parallel, we get the following.
ceq = ∑ici
Consider a circuit with three capacitors connected in series. The capacitances are C₁ = 2.3μF, C₂ =1.8μF, and C₃ =5.1μF.
What is the equivalent capacitance (in μF ) of the three capacitors?
