Question

which statements correctly describe what happens in a circuit with a closed switch and with an open switch? (select all that apply.) a. a closed switch allows current to flow through the circuit, making the load work. b. an open switch allows current to move freely, so the device stays on. c. a closed switch is like a drawbridge that’s down, letting cars (electrons) cross. d. an open switch stops the flow of current, so the load stays off. e. an open switch is like a drawbridge that’s down, allowing electrons to move.

Explanation:

A closed - switch completes the circuit path, enabling current flow and making the load work, similar to a lowered drawbridge allowing electrons (cars) to cross. An open - switch breaks the circuit path, stopping current flow and keeping the load off.

Answer:

A. A closed switch allows current to flow through the circuit, making the load work.
C. A closed switch is like a drawbridge that’s down, letting cars (electrons) cross.
D. An open switch stops the flow of current, so the load stays off.
