The fundamental electrical terms are:

charge q in units of Coulombs and Volts V in units of Volts.

The other untis are Energy U=qV and electric field E = -dV/dr in units of volts/meter and I current I = q/t charge per second.

The other units of importance are E = cB = zH = zcD where B is volt-sec/m^2 and H= I/m is and D=q/m^2 and z is the free space impedance in 375 Ohms and c is the speed of light, 3E8 meters/second..
