Point Charge Electric Fields and Voltages

Point charge electric fields can be combined by vector addition to give a net electric field. Their voltages can just be added since voltage is a scalar quantity.

At the designated field point:
P: [,] m

a source charge
q1 = x10^ C
at position x=, y= m
will produce an electric field
E1x = x10^N/C,
E1y = x 10^N/C
and a voltage
V1 =x 10^ V

A second source charge
q2 = x 10^ C
at position x=, y= m
will produce an electric field
E2x = x10^N/C,
E2y = x 10^N/C
and a voltage
V2 =x 10^ V

The resultant electric field at point P is the vector sum of the fields:

Ex = x10^, Ey = x10^N/C ,
or E = x10^ N/C at angle degrees.

The resultant voltage is simply the sum of the individual voltages:

V = V1 + V2 = x10^V

You may enter data for the sources and their locations, or you may click on one of the supplied examples at left and then modify the parameters.
