Click on one of the wires and click on the trash can to delete the wire. What happens to the light bulbs? They both stay lighted. The right bult goes out, the left one stays on. They both go out. The left bult goes out, the right one stays on.

## Step 1<br />This problem is about understanding the basic principles of electrical circuits. In a series circuit, all components are connected in a single path, so the current flows through each component one after the other. If any component is removed or disconnected, the current cannot flow, and the entire circuit stops working.<br /><br />## Step 2<br />In this case, the light bulbs are connected in a series circuit. When one of the wires is clicked and the trash can is clicked to delete the wire, the circuit is broken.<br /><br />## Step 3<br />As a result, the current cannot flow through the circuit anymore, and all the light bulbs go out.
