This may be appreciated by looking at the units for each. The unit of electric field in the MKS system of units is newtons per coulomb, N/C, while the magnetic field (in teslas) can be written as N/(C⋅m/s). The dividing factor between the two types of field is metres per second (m/s), which is velocity.
The newton (N) is equal to one kilogram-metre per second squared (1 kg⋅m⋅s −2). The pascal (Pa) is equal to one newton per square metre (1 N⋅m −2). The joule (J) is equal to one newton-metre (1 N⋅m). The watt (W) is equal to one joule per second (1 J⋅s −1). The coulomb (C) is equal to one ampere second (1 A⋅s).
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). [ 1 ] [ 2 ] It is defined to be equal to the electric charge delivered by a 1 ampere current in 1 second .
[6]: 479 The field lines are a representative concept; the field actually permeates all the intervening space between the lines. More or fewer lines may be drawn depending on the precision to which it is desired to represent the field. [8] The study of electric fields created by stationary charges is called electrostatics.

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles .
