Attached Figure / Diagram
A
12W
B
24W
C
32W
D
40W
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Total resistance = resistance in series + resistance in parallel
= 4 + (\(\frac{4 \times 4}{4 + 4}\)) = 6\(\Omega\)
Total power drawn = \(\frac{V^2}{\text{R}}\) = \(\frac{12^2}{6}\) = 24W
