Current begins to flow through the tungsten filament of the wire. Because of its high resistance, the wire heats up till the point that it starts glowing, producing light from the bulb.
wiring diagram of one bulb in two switches.. example, if switch a- on then switch b- off the bulb is on, switch a- off then switch b- on the bulb is on, switch a- on then switch b- on the bulb is off, switch a- off then switch b- off the bulb is off..
If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
It is generally not recommended to use a G9 bulb on a dimmer switch unless the bulb is specifically marked as dimmable. Using a non-dimmable bulb on a dimmer switch can cause flickering, buzzing, and even damage to the bulb or the dimmer switch. Always check the bulb packaging to ensure it is compatible with dimmer switches before using them together.
It depend on where the switch is located in the circuit.
There could be a series of problems. First, are all the wires hooked up? Is the bulb burned out? Is it just the switch that is not working? You should go and put in a new bulb, and see if it was just burned out.
The surrounding area adjacent to the light bulb becomes easier to see.

When you flip a switch on a flashlight, you complete an electrical circuit that allows a current to flow from the battery to the light bulb. This causes the light bulb to emit light and illuminate the surroundings.
Unscrewing any bulb in a series circuit turns them all off. This is the same as opening the switch that controls them.
A light bulb dimmer switch works by controlling the amount of electricity flowing to the light bulb. By adjusting the voltage, the dimmer switch can regulate the brightness of the light bulb.

Switch
When the light bulb stays on when the switch is off, it is likely due to a wiring issue or a faulty switch that is not properly cutting off the electricity flow to the bulb.
If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
It is generally not recommended to use a G9 bulb on a dimmer switch unless the bulb is specifically marked as dimmable. Using a non-dimmable bulb on a dimmer switch can cause flickering, buzzing, and even damage to the bulb or the dimmer switch. Always check the bulb packaging to ensure it is compatible with dimmer switches before using them together.
It is a safety concern. With the switch before the bulb, the bulb is completely isolated from the potential source when the switch is turned off. With the switch behind the bulb, even if the switch is turned off, the potential source is still at the bulb. If any of these lamp holder parts touch the ground when removing the bulb the circuit will short out and trip the breaker. If you are grounded and touch any of the lamp holder parts you will get a nasty shock.
