A 6.00-μf parallel-plate capacitor has charges of 40.0 μc on its plates. how much potential energy is stored in this capacitor?
dedylja [7]

Thew energy stored in a capacitor of capacitance C and voltage between the plates V is

E=\frac{1}{2} CV^2=\frac{1}{2C} Q^2.

Substituting numerical value

E=\frac{1}{2*6*10^{-6}} (40*10^{-6})^2\\ E=133.33\; \mu J

In a chemical reaction, the total charge of the reactants must be
MA_775_DIABLO [31]

the same with that of products

Explanation:

In a chemical reaction, the total charge of the reactants must be the same with that of products.

Charges must be conserved or balanced in chemical reactions.

  • In both acidic and basic/neutral medium electrons are used to balance the charge.
  • The appropriate number of electrons is added to the side with a larger charge.
  • One electron is used to balance each positive charge.
  • This ensures that the sum of charges on both sides the same.
