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 = (2 + 3i) amperes and R = (9 + 5i) ohms.
A. (3 + 37i) volts
B. (37 + 3i) volts
C. (3 - 37i) volts
D. (37 - 3i) volts
