On a 3 way circuit both switches must be in the same position for the circuit to be complete and the lights to work. When you add a 4/way or intermediate switch to the middle of the circuit the 4/way switch has 2 positions. One position closes the circuit and the other position opens the circuit. In other words the current is passing through or it is not.
The ability of an object to transfer electric current is conductivity.
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
Create an electric current.
All metals
The ability of a material to transfer heat is called thermal conductivity, while the ability to transfer an electric current is known as electrical conductivity.
The ability of an object to transfer electric current is determined by its electrical conductivity. Materials with high electrical conductivity, such as metals, allow electric current to flow easily through them, while insulating materials have low electrical conductivity and inhibit the flow of current. Conductors like copper and silver are widely used for their high electrical conductivity.
A: Because it has no connection or open as we say
Electric current flows in the b connection due to the movement of electrons from the negative terminal to the positive terminal of the power source. This flow of electrons creates a closed loop circuit, allowing the current to pass through the b connection and power the device or component it is connected to.

Mainly energy. Note that the electric current involves movement of electrons or other particles that are matter; however, the electric current "is" not so much the electrons (they exist whether there is a current or not; it is more precise that the current "is" the electrons' movement. Although even this may be an over-simplification.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
An electric charge is surrounded by an electric field, which exerts a force on other electric charges in its vicinity. This electric field can interact with other electric fields, leading to the transfer of energy and the flow of electric current.
