Which choice most accurately explains the role of a circuit component in preventing a circuit from getting too hot and catching fire?
(Select all that apply)

1-A fuse can be used to prevent a circuit from getting too hot. It will melt if the current gets too high, resulting in an open circuit. Then the current will stop moving through the circuit.
2-A thicker wire can be used to prevent the circuit from getting too hot. A thicker wire will decrease the current of the circuit. The current will continue to move, but at a lesser rate.
3-A battery can be used to prevent a circuit from getting too hot. A battery will decrease the current of the circuit. The current will continue moving through the circuit, but at a lesser rate.
4-A circuit breaker can be used to prevent a circuit from getting too hot. A switch in the breaker will open if the current gets too high, resulting in an open circuit. Then the current will stop moving through the circuit.

  1. Not #2. A thicker wire offers less resistance.
    Now do some thinking.
