Drift Velocity (with current and conductor section area)

The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. It can also be referred to ... more

Intensity - Mathematical description

In physics, intensity is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the ... more

Electric Intensity

Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge ... more
