PDF	Chapter 2 Electric Fields It follows from Coulomb's law that the electric field at point r due to a charge q located at the origin is given by E = k q r2 r (2 3) where r is the unit

What is the formula for the constant electric field?
The Electric field formula that gives its strength or the magnitude of electric field for a charge Q at distance r from the charge is E = k Q r 2 , where k is Coulomb's constant and the units of the electric field are Newtons/Coulomb.
What if the electric field is constant?
It is obvious that if some charge is subjected to a constant electric field, it will start to move.
As the field E does not change with time, an ordered motion of charges is observed.
This phenomenon is called the electric current.
What is the work in a constant electric field?
Work and Voltage: Constant Electric Field
The electric field is by definition the force per unit charge, so that multiplying the field times the plate separation gives the work per unit charge, which is by definition the change in voltage.
The equation E = k Q / r 2 E = k Q / r 2 says that the electric field gets stronger as we approach the charge that generates it.
For example, at 2 cm from the charge Q (r = 2 cm), the electric field is four times stronger than at 4 cm from the charge (r = 4 cm)._{26 mar. 2020}
