Customer ServiceInductors store energy in the magnetic field generated when current passes through them. When the supply is removed, the collapsing magnetic field induces a current flow in the same direction that it was traveling when it generated the magnetic field in the first place.

Customer ServiceThe energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.The voltage V is proportional to the amount of charge which is already on the capacitor.

Customer ServiceWhen the switch is closed to connect the battery to the capacitor, there is zero voltage across the capacitor since it has no charge buildup. The voltage on the capacitor is proportional to the charge. Storing energy on the capacitor involves doing work to transport charge from one plate of the capacitor to the other against the electrical forces.

Customer ServiceThe voltage on the capacitor is proportional to the charge Storing energy on the capacitor involves doing work to transport charge from one plate of the capacitor to the other against the electrical forces. As the charge builds up in the charging process, each successive element of charge dq requires more work to force it onto the positive plate.
Give the capacitors equal capacities and assign a voltage to the charged capacitor. Calculate its stored energy. Close the switch. Now the capacitors will have equal voltages; each can be up to 1/2 the original voltage. Now calculate the stored energy in each and add them together. You will find that at least half the energy is missing.
It shows that the energy stored within a capacitor is proportional to the product of its capacitance and the squared value of the voltage across the capacitor. ( r ). E ( r ) dv A coaxial capacitor consists of two concentric, conducting, cylindrical surfaces, one of radius a and another of radius b.
The magnitude of energy stored in the capacitor is: E = 1 2 C Δ V 2, so a change in potential difference will cause a change in energy stored. So when the switch is closed and let to equilibrium the resistors will be in series increasing total resistance causing the total current to be less than when it was when the switch was opened.
A capacitor is charged. It is then connected to an identical uncharged capacitor using superconducting wires. Each capacitor has 1/2 the charge as the original, so 1/4 the energy - so we only have 1/2 the energy we started with. What happened? my first thoughts were that the difference in energy is due to heat produced in the wire.
As the capacitance of the contacts at a initial distance can not be zero and as the distance must reach zero to close the contact, the capacity of this capacitor reached infinity and all the energy stored in this capacitor will be dissipated. as this charged capacitor stores energy and a short circuit will not be consistant with this condition.
