Electrical energy Electrical energy is caused by moving electric charges called electrons. The faster the charges move, the more electrical energy they carry. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy.

Explanation:
Switch key A switch is an electric component that opens or closes a circuit. We know that electricity can only pass across a circuit if it is closed. The switch is usually wired in series with the load it is attempting to control.

If a piece of soft iron is placed inside the coil n number of turns and current is passed in the coil from a battery, what name is then given to the device so obtained?
1 Spectrometer
2 Gravitometer
3 Barometer
4 Electromagnet
Explanation:
Electromagnet A solenoid is a long coil containing a large number of close turns of insulated copper wire wound on a conducting or non - conducting material. In this case, we consider a coil wound on a soft iron bar called the core. When the circuit is closed by pressing the key, a steady current flow through such a device, the magnetic fields produced by the solenoid are similar to the magnetic field produced by a magnet and hence it is called as an Electromagnet. The strength of an electromagnet is related to factors stated below:
