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

Respuesta :

tramserran

Answer: 10 + i

Step-by-step explanation:

E = IZ

  = (3 + 2i)(2 - i)

  = 6 - 3i + 4i - 4i²

   = 6 + i - 4(-1)

    = 6 + i + 4

    = 10 + i
