Question

in the series circuit below, the switch is in the open, or off, position. notice that the bulbs are not glowing at all. what happens when you close the series circuit with a switch? the current stops flowing. the current flows. the lightbulbs stay off.

Explanation:

In a series circuit, when the switch is closed, it completes the circuit path. According to the basic principle of electric circuits, a closed circuit allows electric current to flow. When current flows through the light - bulbs in a series circuit (assuming no other faults like bulb burnout), the light - bulbs will glow. The first option "The current stops flowing" is incorrect because closing the switch allows current to flow, not stop it. The third option "The lightbulbs stay off" is also wrong as a properly functioning closed series circuit with working bulbs should have the bulbs on.

Answer:

The current flows.
