Question

39. S.I unit of intensity of electric field is :
​

Answer 1

Answer:

Electric field intensity is a vector field we assign the symbol E and has units of electrical potential per distance; in SI units, volts per meter (V/m).

Answer 2

Your answer:

The SI unit of an electric field intensity is volt/metre.

Explanation:

We know that electric field intensity is the force on a positive unit charge placed in a electric field. Electric potential means the work required to bring a unit positive charge from infinity to a point existed in a electric field. We know that the SI unit of electric potential is Volt. From the above definition we can say that multiplication of displacement (r) with the electric field intensity (E) will give us the electric potential(V). More specifically the electric field intensity is one kind of force and the electric potential is one kind of work so if we multiply the displacement with the force we will get the work done. Hence the relation will be E∗r=V . You can also refer the attached image for advanced understanding.
