Why does a light go out when you turn off the wall switch?


A.
The switch changes the direction of the flow of electrons.

B.
The switch causes a break in the circuit.

C.
The switch changes the circuit from series to parallel.

D.
The switch absorbs the electrical energy.

The answer is B

B. The switch causes a break in the circuit.

When you turn off the wall switch, it causes a break in the circuit, interrupting the flow of electricity. This break prevents the current from reaching the light bulb and as a result, the light goes out.

The correct answer is B. The switch causes a break in the circuit.

When you turn off a wall switch, it physically moves a lever or flip a mechanism inside the switch to disconnect the flow of electricity. This interruption in the circuit prevents the current from reaching the light bulb, causing it to go out.

To understand this concept, it is helpful to have a basic understanding of an electrical circuit. An electrical circuit consists of a power source (such as a battery or a power outlet), conductive wires that connect various components, and a load (such as a light bulb) that converts the electrical energy into light or another form of energy.

In a closed circuit, which means the circuit is complete and unbroken, electrons flow through the wires from the power source to the load and back again. This continuous flow of electrons allows the load, in this case, the light bulb, to receive the necessary electrical energy to produce light.

When you flip the wall switch to the off position, it opens or breaks the circuit. This means that the path for the flow of electrons is interrupted, and they are unable to reach the light bulb. As a result, the light bulb goes out.

So, to summarize, when you turn off the wall switch, it causes a break in the circuit, preventing the flow of electricity and causing the light to go out.
