Question 12 • Physical Science

In a movie, a character cuts a wire, which stops the countdown timer of a bomb. What does cutting the wire do to the circuit?

Answer
A
It opens the circuit so that electric charges do not flow to the timer.
B
It closes the circuit so that electric charges flow to the timer.
C
It closes the circuit so that electric charges do not flow to the timer.
D
It opens the circuit so that electric charges flow to the timer.

Explanation

A complete, closed circuit lets electric charges flow. Cutting a wire breaks that path, opening the circuit, so charges no longer flow to the timer. Therefore, the correct choice is “It opens the circuit so that electric charges do not flow to the timer.”
