Question

component of a circuit changes, as shown below. how would this change affect the electric circuit? a switch is closed, so the circuit would be incomplete and broken and the lights in the circu would not shine. a switch is closed, so the circuit would be compl and unbroken and the lights in the circuit would shine. a switch is opened, so the circuit would be incomplete and broken and the lights in the circuit would not shine. a switch is opened, so the circuit would be comple and unbroken and the lights in the circuit would shine.

Explanation:

1. Analyze the switch state change: The left diagram shows an open switch (gap between contacts), the right shows a closed switch (contacts connected).
2. Recall circuit principles: A closed switch completes the circuit (continuous path for current), an open switch breaks it.
3. Evaluate options:

• First option: Closed switch + incomplete circuit is wrong (closed = complete).
• Second option: Closed switch → complete circuit → current flows → lights shine. This matches.
• Third and fourth: Say switch is opened, but the diagram shows closing, so these are wrong.

Answer:

B. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. (Note: Assuming the second option is labeled B as per typical multiple - choice formatting, with the full text as described.)
