Asked by cvf

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?
4 – i
4 + i
8 + i
8 + 7i

E = (3 + 2i)(2 − i) = 6 − 3i + 4i − 2i^2 = 6 + i + 2 = 8 + i.
