Final answer:
To calculate the power absorbed by the 3.3 ohm resistor, use Ohm's law to find the current and then apply Joule's law to find the power dissipated.
Step-by-step explanation:
To determine the power absorbed by the 3.3 ohm resistor, we use Joule's law, P = I²R. Given that the voltage drop V3 across resistor R3 is 6 V, we can find the current I3 using Ohm's law (V = IR), which yields I3 = V3/R3. By rearranging Ohm's law to solve for current: I3 = 6 V / 3.3 Ω. Calculate the current and then apply it to the power formula to find the power dissipated by the 3.3 ohm resistor.
