# The relationship between voltage, E, current, I, and resistance, Z, is given by the equation E = IZ. If a circuit has a current I = 3 + 2i and a resistance Z = 2 – i, what is the voltage of the circuit?

(1) Answers

I=3+2i Z=2-i i=√-1 i²=-1 E=IZ=(3+2i)(2-i)=6-3i+4i-2i²=6+i-2(-1)=6+i+2=8+i. Solution: E=8+i
