In a distant radio transmitter, the magnitude of the E field is often much less than 1 V/m. Fractional and multiple values of volt per meter Volt per meter is a vector quantity since it is characterized by both magnitude and direction. This strength also decreases as the distance from the source increases and if there are shields, such as walls, houses or trees, in place. The higher the source voltage, the higher the strength of the E field. This example shows that volt per meter is affected by both the distance between the conductor's plates and the voltage applied between them. The E field can now be measured as the following: However, a higher voltage (say 3 volts) is applied between them. The distance between the plates remains 1.5 m. Now, if the plates are moved toward each other so that the distance between them is 1 millimeter, the E field changes to the following: The E field strength can be expressed in terms of V/m as the following: Suppose 1.5 V are applied across the capacitor whose plates are 1.5 m apart. Simply put, if 1 V is applied between two infinite parallel planes spaced 1 m apart, the electric field strength is 1 volt per meter. Volt per meter indicates the strength or intensity of the E field in the EM field. This EMF contains both a magnetic (M) and electric (E) component. When electricity flows through an electrical conductor, it produces an electromagnetic field (EM field or EMF). In base Standard International ( SI) units, 1 V/m is the equivalent of 1 meter per kilogram per second cubed per ampere.
An E field of 1 V/m refers to a potential difference of 1 V between two points 1 m apart. Volt per meter is the standard unit of electric field (E field) strength.
