Question 70: Electrostatics & Capacitance

Question

Two capacitors $$C_1$$ and $$C_2$$ are charged to 120 V
and 200 V, respectively. When they are
connected in parallel, it is found that potential
on each one of them is zero. Therefore,

Accepted Answer

Given, $$V_1=120$$V, $$V_2=200$$V
Since, potential on each capacitor is zero when they are connected in parallel. Hence, charge on each capacitor must be equal with unlike polarities together.
i.e. $$q_1=q_2$$
$$\Rightarrow C_1V_1=C_2V_2$$
$$\Rightarrow C_1	imes120=C_2	imes200$$
$$\Rightarrow 3C_1=5C_2$$

Answer

$$5C_1=3C_2$$

Answer

$$3C_1=5C_2$$

Answer

$$3C_1+5C_2=0$$

Answer

$$9C_1=4C_2$$
