\(142 \) The relationship between voltage, \( E \)...

\(142 \) The relationship between voltage, \( E \) , current, \( l , \) and resistance, \( Z \) , is given by the equation \( E = I Z \) . If a circuit has a current \( I = 3 + 2 i \) and a resistance \( Z = 2 - i , \) what is the voltage of the circuit? 

\( 4 - i \) 

\( 4 + i \) 

\( 8 + i \) 

\( 8 + 7 i\)
