by using compass.
A compass can detect an electric current because a moving electric charge produces a magnetic field around it. When an electric current flows through a wire, it creates a magnetic field that can be detected by the compass needle. This phenomenon is known as electromagnetism.
An electrostatic field meter is typically used to detect a static charge. It measures the strength of the electric field created by the charge and can indicate if a static charge is present in a given area.
Depends on the electrical field, but the most common way to tell is the metallic smell of ionized oxygen or ozone, a tingly feel on the skin, and hair standing on end. But that's only for strong electric fields. For weak electric fields the use of a some sort of meter is required.
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.

The electric field equation describes the strength and direction of the electric field at a point in space. Voltage, on the other hand, is a measure of the electric potential difference between two points in an electric field. The relationship between the electric field equation and voltage is that the electric field is related to the gradient of the voltage. In other words, the electric field is the negative gradient of the voltage.
It's the electric field.
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
No, voltage is not the derivative of electric field. Voltage is a measure of electric potential difference, while electric field is a measure of the force experienced by a charged particle in an electric field.
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.
The amplitude of the associated electric field refers to the maximum strength or intensity of the electric field. It represents the peak value of the electric field's magnitude.
Electric field lines represent the direction of the electric field at any point in space. If there were sudden breaks in the field lines, it would imply sudden changes in the electric field strength, which is not physically possible. The electric field must vary continuously and smoothly in space.
