Use Ohm's Law E=I*R

E=I%2AR=%282-3%2Ai%29%2A%283%2B5%2Ai%29
E=6%2B10%2Ai-9%2Ai-15%2Ai%5E2 and since i%5E2=-1 this can be simplified to
E=6%2B1%2Ai%2B15=%2821%2Bi%29+volts
One small comment. Here, R=(3+5i) which should strictly be called Z (the 'Impedance' which is complex) where R is the Real part of Z...
