Complex numbers are used in electronics to describe the current in an electric circuit. Ohm's law relates the current in a circuit, I, in amperes, the voltage of the circuit, E, in volts, and the resistance of the circuit, R, in ohms, by the formula 
Solve the problem using this formula.Find E, the voltage of a circuit, if I = (18 + i) amperes and R = (3 + 2i) ohms.
A. (52 - 39i) volts
