If potential difference is reduced to half, the energy of capacitance will be

Respuesta :

The formula of the capacitance is

[tex]C=\dfrac{q}{V}[/tex]

If you half the potential difference, you'll have the new capacity

[tex]C_1 = \dfrac{q}{\frac{V}{2}}=\dfrac{2q}{V} = 2\cdot\dfrac{q}{V}=2C[/tex]

So, if you half the potential difference, the capacitance doubles.
