Ama-capacitor axhunywe ngokufana ukuze umehluko ongaba khona ku-capacitor C₃ (V₃) = umehluko ongaba khona ku-capacitor C₂ (V₂) = umehluko ongaba khona ku-capacitor C₁ (V₁) = umehluko ongaba khona ku-capacitor elinganayo (V) = 4 Volt

Ukushaja kukagesi ku- capacitor C1 _:

Q ₁ = C ₁ V ₁ = (4 x 10 ^-6 )(4) = 16 x 10 ^-6 C

Q ₁ = 16 μC

Ukushaja kukagesi ku- capacitor C2 _:

Q ₂ = C ₂ V ₂ = (2 x 10 ^-6 )(4) = 8 x 10 ^-6 C

Q ₂ = 8 μC

Ukushaja kukagesi ku- capacitor C3 _:

Q ₃ = C ₃ V ₃ = (3 x 10 ^-6 )(4) = 12 x 10 ^-6 C

Q ₃ = 12 μC

(b) Ishaja kagesi ku-capacitor elinganayo

Q = Q ₁ + Q ₂ + Q ₃

Q = 16 μ C + 8 μ C + 12 μ C = 36 μ C

Isixazululo esihlukile:

I-capacitance efanayo:

C = C ₁ + C ₂ + C ₃

C = 4 μF + 2 μF + 3 μF = 9 μF

C = 9 x 10 ^-6 F

Umehluko ongaba khona ku-capacitor efanayo:

V ₁ = V ₂ = V ₃ = V = 4 Volt

Ishaja kagesi ku-capacitor efanayo:

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

Q = 36 μC
