Volt or voltage-measurement of electricity in terms of pressure symbol (V) also (E)

Amp or ampere:  Refers to the rate at which electrons flow, one amp is equal to 6.24 x 10 to the 18th electrons moving past a point in one second. (current symbol (I))

Resistance: measured in ohms also referred to as impedance.  It is the resistance to the flow of electrons. symbol (R)
