If a light bulb is burned out and the switch is on are you still using electricity?
A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it.
If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on
It may still use power if it is a lighted switch.

Cutting Down Your Average Electricity Bill Per Month?
One thing that can really increase your electricity bill, something that you might not even be aware of, is a switch that is left on when a light bulb is burned out. It does not matter that there is no light being produced. If the switch is on, all of the electricity is still being routed to that socket. You are paying for a light that you cannot see. To cut down your average electricity bill per month, make sure that you always replace your light bulbs as soon as they burn out so that you know they are off.
What happens when a switch circuit is opened?
When a switch is closed the path through the circuit is continuous.
Do light sockets without bulbs in them still use energy when their switch is turned on?
No, light sockets without bulbs do not consume energy when the switch is turned on because there is no electrical load present to draw electricity. The circuit remains open when there is no bulb, so no electricity flows through it.
Does a light switch produce AC or DC electric currents?
Alternating (AC) and direct (DC) currents are different forms of electricity. It is universal nowadays to have AC in all houses because the electricity grid distribution system is all AC. DC was used by Edison and continued for some years but is now discontinued. It is still used in vehicles where 12 V DC is the normal system. A light switch simply interrupts the current or makes the circuit as required, and both AC and DC need to have switches.
Is electricity wasted if we switch on a socket and do not use it?
Yes, electricity is wasted if a socket is switched on but not being used because the electricity is still flowing through the circuit even though no device is drawing power.
Does electricity flow through a light when the light is turned off?
The OFF position on the light switch interrupts the flow of electricity to the light bulb. If the switch is ON, there is always electricity at the light socket, even when the light bulb is removed. if the lamp is still pluged in electricity is still flowing through the lamp even if it is off or on

Does an outlet controlled by a light switch still pull energy when the light switch is off?
No.
Does a light still you electricity if there is no bulb?
No, a light fixture does not consume electricity if there is no bulb in it. The bulb is what generates light when electricity passes through it, so without a bulb, there is no circuit to complete and no electricity is being used.
My 2000 Dodge Neon displays a FUSE light at startup on the dash. I can't find the problem fuse.?
I had a 2000 Plymouth Neon and I saw the same ''FUSE'' light on all the time, check the light switch in all of the doors, if the FUSE light is still on, check the interior light bulb, maybe is burned...
You replaced brake switch lights still on?
Check the petal and make sure that the plastic part that touches the brake light switch when the petal is in contact with the brake light switch is still on the petal, if it is missing you will need to replace it, so the petal will make correct contact with the brake light switch.

How was the light switch created?
The original light switch was invented in 1884 by John Holmes. This switch was made to prevent "arcing" of the electrical circuit, and the design is still in use today.
How do you replace light on heated seats switch on a 2000 Intrigue Light on switch for drivers seat OS out but light for passenger seat works?
If the heater still works the bulb is just burn out. I doubt you can change the light you will have to replace the switch.
