Dado o circuito abaixo, determine a tensão equivalente de Thévenin entre os pontos a e b.
The image shows an electrical circuit with a 12V voltage source, a 2A current source, and several resistors. The circuit includes two 6Ω resistors in series with the voltage source, a 4Ω resistor connected between points a and b, and another resistor in parallel with the 4Ω resistor.
A) V_{Th} = 0,75 V
B) V_{Th} = 2,25 V
C) V_{Th} = 3,5 V
D) V_{Th} = 4,75 V
E) V_{Th} = 6,0 V
