Question 50: Electrostats & Capacitance

Question

The figure shows a network of five capacitors connected to a 20 V battery. Calculate the charge acquired by each 10 $$\mu$$F capacitor.

Accepted Answer

When two capacitors are connected then their common potential difference is
$$V=\frac{C_1 V_1+C_2 V_2}{C_1+C_2}$$
Given, $$C_1=2 \mu \mathrm{F}, V_1=14 \mathrm{~V}, C_2=5 \mu \mathrm{F}, V_2=0~V$$
$$	herefore \quad V=\frac{2 	imes 14+5 	imes 0}{2+5}=4 V$$

Answer

$$2 	imes 10^{-4} \mathrm{C}$$

Answer

$$4 	imes 10^{-4} \mathrm{C}$$

Answer

$$6 	imes 10^{-4} \mathrm{C}$$

Answer

$$1 	imes 10^{-4} \mathrm{C}$$
