V comes from "voltage" and E from "electromotive force". E means also energy, so V is chosen.
Energy = voltage × charge. E = V × Q. Some like better to stick to E instead to V, so do it.
 
V = R × I = P / I = √P × R      I = V / R = P / V = √P / R
R = V / I = V2 / P = P / I2      P = V × I = R × I2 = V2 / R
