Final answer:
The voltage of the circuit is 12 + j22 V.
Step-by-step explanation:
To find the voltage of the circuit, we can use Ohm's Law, which states that voltage is equal to current multiplied by resistance. In this case, the current is 3 + j4 amps and the resistance is 4 - j6 ohms. So, the voltage would be:
Voltage = Current x Resistance
Voltage = (3 + j4) x (4 - j6)
Voltage = 12 + j22
Therefore, the voltage of the circuit is 12 + j22 volts.
