Final answer:
To find the voltage vo, use Ohm's law and the given total resistance. The current (I) is 2.35 A, and the total power supplied is 28.2 Watts.
Step-by-step explanation:
In order to find the voltage vo, we should first calculate the total current (I) using Ohm's law, which states that V = IR. Given the total voltage (V) of 12.0 volts and the total resistance (Rtot) of 5.11 ohms, we get:
I = V / Rtot = 12.0 V / 5.11 Ω = 2.35 A
Next, the total power supplied in the circuit can be found by the formula P = VI, which yields:
P = 12.0 V * 2.35 A = 28.2 Watts
This is the power supplied by the voltage source.
