Suppose you have two capacitors and want to use them to store the maximum amount of energy by connecting them across a voltage source. You should connect them

Respuesta :

Answer:

Connect them in parallel

Explanation:

The energy stored by two capacitors connected to the same voltage source is given by

[tex]U=\frac{1}{2}C_T V^2[/tex]

where

[tex]C_T[/tex] is the total capacitance of the two capacitors

V is the voltage of the source

In order to maximize the energy stored U, we need to maximize [tex]C_T[/tex]. We have:

- In parallel, the total capacitance is given by the sum of the individual capacitances:

[tex]C_T(p) = C_1 + C_2[/tex]

- In series, the total capacitance is given by:

[tex]C_T(s)=\frac{1}{\frac{1}{C_1}+\frac{1}{C_2}}[/tex]

Comparing the two equations, we notice that [tex]C_T(p)>C_T(s)[/tex], so the parallel configuration is the one that maximizes the energy stored.
