Conductors are materials that passes a current along easily. Conductors are materials that include copper, silver, aluminum, and steel. Insulators are materials that are poor conductors and include glass, rubber, and ceramic.
Material with low conductance such as rubber, plastics and so forth.
A material that passes current easily is called a conductor. The best conductors are metals.
good conductors like metals
Because metals are the good conductors of current. the conduction band and the valance band are overlap on each other,so when the current passes from the metal because of overlapping on both the bands current passes easily.
When all light passes through a material, it is called transparent. This means that the material allows light to pass through with little or no distortion, making objects on the other side visible.
Refraction
Electric current passes through a conductor when a voltage is applied across it, creating an electric field that pushes charged particles (electrons) through the material. The electrons move in response to this field, flowing from areas of higher voltage to areas of lower voltage. The amount of current that passes through the conductor depends on the material's conductivity and the applied voltage.
the current which has negative value n passes through the diode is called as diode reverse current
The material you are referring to is typically called a medium, such as air, water, or glass. As light passes through the medium, it interacts with the atoms or molecules in the material, causing it to scatter or refract, which can lead to the spreading out of light.
Refraction.
The bending of light as it passes from one material to another is called refraction. Refraction occurs when light travels through materials of different densities, causing the light to change direction.
The bending of light as it passes through a material is called refraction. This occurs due to a change in speed of light as it moves from one medium to another, causing it to change direction.
