Question 2

Select an answer from the options below and click Submit.

From paragraphs 12 and 13, select the section of text that the author used to create the visual.

A. If the filament burns out, however, the high temperature from the burnout will cause the substance coating the shunt to melt off, revealing the lower resistance wire beneath…current passes along the shunt, keeping the circuit closed, and the remaining lights burning. B. A shunt is any device that allows current to continue flowing through a circuit by creating a path of lower resistance than the original path. In incandescent holiday lights, shunts are small wires wrapped beneath the filament. C. Electricity cannot pass across the shunt as long as the filament exists, because the coating gives the shunt a higher resistance initially than the filament, and the electrical current avoids the shunt in order to find the path of least resistance, through the filament. D. In incandescent holiday lights, shunts are small wires wrapped beneath the filament. Initially, they are coated with a substance that makes them an insulator.

Answer: Correct!

Answer: Incorrect. The answer is A.

The filament burns out, causing the substance coating the shunt to melt away. This process is illustrated through the bright orange light and arrow paths.

Next, the current passes along the shunt, keeping the circuit closed, and the remaining lights burning. This process is illustrated through the dull grey light and the arrow paths.
