Question 386: Electrostatics & Capacitance

Question

Two capacitors $${C_1}$$ and $${C_2}$$ are charged to $$120$$ $$V$$ and $$200$$ $$V$$ respectively. It is found that connecting them together the potential on each one can be made zero. Then

Accepted Answer

For potential to be made zero, after connection
$$120{C_1} = 200{C_2}$$
$$\left[ {\,\,} \right.$$ as $$\left. {C = {q \over v}\,\,} \right]$$
$$ \Rightarrow 3{C_1} = 5{C_2}$$

Answer

$$5{C_1} = 3{C_2}$$

Answer

$$3{C_1} = 5{C_2}$$

Answer

$$3{C_1} + 5{C_2} = 0$$

Answer

$$9{C_1} = 4{C_2}$$
