6 FAQs about [Electric energy lost when capacitors are connected in parallel]

What happens when a capacitor is placed in parallel?

Suppose an uncharged capacitor is placed in parallel with another already charged capacitor of the same capacitance then the charge is split in half between the two capacitors and the total energy is reduced by half. Where is the energy lost? Is it lost during the transfer of charge between the two capacitors or in some other manner?

How is energy lost in a capacitor?

Energy is lost primarily in the connection wires and internal resistances of the capacitors, while the charge is being transferred. A transfer of charge is a current and a current produces heating when passing through a conductor.

What happens when a capacitor is connected to a circuit?

At the moment the capacitors are connected, in accord with ideal circuit theory, there should be an impulse (infinitely large, infinitely brief) of current that instantaneously changes the voltage on both capacitors. But this ignores the self-inductance of the circuit and the associated electromagnetic effects.

What happens if two capacitors are connected together?

What's not being considered is the energy lost to radiation at the moment the two capacitors are connected together. At the moment the capacitors are connected, in accord with ideal circuit theory, there should be an impulse (infinitely large, infinitely brief) of current that instantaneously changes the voltage on both capacitors.

What happens to the energy supplied to the first capacitor?

The total energy supplied to the first capacitor will be evenly distributed (minus the losses) between the two capacitors. The only energy 'lost' is that which is lost due to resistance heating, etc., based on the parameters of the given circuit. An analogy can be drawn with two buckets - - one empty and one full of water.

How to solve a problem with a capacitor?

Hint: The given problem can be solved by using the concept of the charging and discharging of the capacitors. Capacitors are devices that store the electrical energy in their electric field.
