Question

A rectangular box of lines has circles with x's in them on the right side and on both top and bottom sides near their right ends. The top circle is a. The right side circle is b. The bottom circle is c. The bottom side has 2 small circles separated by a short segment of the side near the left end. The top side has a stack of short horizontal lines labeled a in its middle, which are from left to right short, very short, short, very short. Use the diagram and the drop-down menu to answer the question. If bulb c burns out A) Bulb a will turn off. B) Bulb b will turn off. C) Bulb c will turn off. D) None of the above.

Answer 1

If bulb c burns out in the given circuit, bulb b will turn off while bulb a will remain lit.

Step-by-step explanation:

In the given circuit diagram, if bulb c burns out, bulb b will turn off. When bulb c burns out, it breaks the circuit and interrupts the flow of current. As a result, no current can reach bulb b, causing it to turn off. However, bulb a will still remain lit because it is connected separately and is not affected by the burnout of bulb c.
