Considere uma fonte de tensão sinusoidal cujo valor instantâneo é dado por:

Consider a sinusoidal voltage source whose instantaneous value is given by:

 v (t) =Vm \cdot  cos ( \omega \cdot t + \phi)  v (t) =Vm \cdot cos ( \omega \cdot t + \phi)

com   f=537 Hz, Vm=22 Volt , φ =2,2 rad

with  f=537 Hz, Vm=22 Volt , φ =2,2 rad

Sendo a amplitude complexa da tensão dada por   \rho \cdot exp (j \alpha)  \rho \cdot exp (j \alpha) indique o valor de ρ

Considering the complex amplitude of the voltage is given by  \rho \cdot exp (j \alpha) \rho \cdot exp (j \alpha) indicate the value for ρ
