Q = Q ₁ + Q ₂ + Q ₃

Q = 16 μ C + 8 μ C + 12 μ C = 36 μ C

Hoʻonā ʻē aʻe:

ʻO ka capacitance like:

C = _C1 + _C2 + _C3

C = 4 μF + 2 μF + 3 μF = 9 μF

C = 9 x 10 ^-6 F

ʻO ka ʻokoʻa hiki ke hana ma ka capacitor like:

V ₁ = V ₂ = V ₃ = V = 4 Volt

ʻO ka uku uila ma luna o ka capacitor like:

Q = CV = (9 x 10 ^-6 )(4) = 36 x 10 ^-6 C

Q = 36 μC
