An electric field is a physical quantity that describes the influence that a charged particle has on other charged particles in its vicinity. It is represented by vector arrows that point in the direction of the force that a positive charge would experience if placed in the field.
Electric potential is the amount of energy required to move a unit positive charge from an infinite distance to a specific point in an electric field. The electric potential is directly related to the electric field, as the electric field is the gradient of the electric potential.
The strength of an electric field is measured in newtons per coulomb (N/C). This represents the amount of force that a unit positive charge would experience if placed in the field. It can also be measured in volts per meter (V/m), as electric field and electric potential are directly related.
An electric field is a vector quantity that represents the force that a charged particle would experience in a given region. On the other hand, electric potential is a scalar quantity that represents the amount of energy required to move a charged particle to a specific point in the electric field.
Yes, electric potential can be negative. This means that the energy required to move a charged particle from an infinite distance to a specific point in the electric field is less than zero, indicating that work is done by the electric field on the particle. This can occur when the electric field is generated by negative charges.
