What resettable device is used to protect electrical circuits? Circuit breaker Circuit interrupter Common fuse Three-way switch

## Step 1<br />The question is asking for a resettable device that is used to protect electrical circuits. The options provided are Circuit breaker, Circuit interrupter, Common fuse, and Three-way switch.<br /><br />## Step 2<br />A circuit breaker is a device that trips when too much current flows through it, interrupting the circuit and preventing to the electrical circuit. It can be reset after it has tripped.<br /><br />## Step 3<br />A circuit interrupter is a device that stops the flow of current in an electrical circuit when it detects an imbalance between the input and output. However, it does not reset itself after it has tripped.<br /><br />## Step 4<br />A common fuse is a device that melts when too much current flows through it, interrupting the circuit and preventing potential damage to the electrical circuit. However, it cannot be reset after it has melted.<br /><br />## Step 5<br />A three-way switch is a type of switch that can be used to control a light or other electrical device from two different locations. It does not protect electrical circuits.
