How is electric field intensity calculated?

The electric field intensity is calculated by dividing the force experienced by a test charge by the magnitude of the charge.

To calculate the electric field intensity at a point in space, we need to know the electric charge that creates the field and the distance from that charge to the point in question. The electric field intensity is a vector quantity, meaning that it has both magnitude and direction. The direction of the electric field is the direction in which a positive test charge would move if placed in the field.

The equation for electric field intensity is E = F/Q, where E is the electric field intensity, F is the force experienced by a test charge, and Q is the magnitude of the test charge. The SI unit for electric field intensity is newtons per coulomb (N/C).

The electric field intensity can also be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. By rearranging this equation, we can solve for the electric field intensity at a point in space.

In summary, the electric field intensity is a measure of the strength of an electric field at a point in space. It is calculated by dividing the force experienced by a test charge by the magnitude of the charge, and can also be calculated using Coulomb's law.
