What two units are used for electric fields? The electric field is also a vector quantity. It has two SI units that are widely used are N/C (Newton per Coulomb) and V/m (Volt per meter).What is Electric Field? The area, space, or field around any point charge is called an electri...
The vector E has the units of N/C. An electric field exists at a point if a test charge placed at rest at that point experiences an electric force. The electric field is said to exist at some point regardless of whether or not a test charge is located at that point. Electric Fields...
The electric field also relates to voltage - a stronger E-field incident upon an antenna will induce a larger voltage difference across the antenna's terminals. However, except for low frequencies, the relationship between E-fields and Voltage is not simple (the voltage is a potential which is...

Magnetic fields are created by permanent magnets or by currents, i.e., by moving electric charges.A moving electric charge is surrounded by an electric field and a magnetic field. In its rest frame, an electric charge generates an electric field, but no magnetic field. Electric and magnetic...
The Electric Flux Density (D) is related to the Electric Field (E) by: [Equation 1] In Equation [1], is thepermittivityof the medium (material) where we are measuring the fields. If you recall that the Electric Field is equal to the force per unit charge (at a distanceRfrom a char...
The horizontal components of the two fields cancel, and the vertical components add. Thus the net electric field points vertically downward, in agreement with the field direction at the corresponding point in Figure 3.11(b). Its magnitude is twice the vertical component of either E→+ or E→...
