When a light switch is turned on in a dc circuit what is the average speed of electrons in the lamp?

But the surprising thing is that the electrons travel VERY SLOWLY. In fact, if the electrons had to get to the lamp before you would see the light, we would wait several seconds in the dark each time we turned on the light.
So the energy transfer in a circuit is wildly different from the electron transfer.

Why do the electrical gadgets stop working when switch is turned off?
A switch breaks the flow of electrons (current).
Diagram of a closed circuit?
a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit
How are parallel circuit lights better than series circuit lights using science facts?
In a parallel circuit, there are multiple paths for electricity to flow. So, if one switch is turned off there is still other paths for electricity to flow so the other lights can remain on. However, in a series circuit there is only one path for the electricity to travel. So, if the switch in a series circuit was turned off the electricity would stop flowing causing all the lights to go out.
Why does a light stay on after switch is turned off?
Either the switch is broken or it doesn't go to that light.
How does electricity flow through a light bulb?
The atoms inside the wire of the lightbulb all have electrons which are pushed from atom to atom when the light is turned on, this is the current. When the electrons are pushed around the circuit they generate lots of heat because the wire in the bulb is so thin, this makes the wire glow white hot which creates the light.
What causes electrons flow when a switch is turned on?
An electric field causes electrons to flow when a switch is turned on.
What causes electrons to flow when a a switch is turned on?
An electric field causes electrons to flow when a switch is turned on.
What causes electrons to flow when switch is turned on?
An electric field causes electrons to flow when a switch is turned on.
What is close circuit and an open circuit?
a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit
What happened when you turned on the switch of the light?
A switch is placed in an electrical circuit in order to place a gap when the switch is off, so the circuit is broken. When the switch is on, the circuit is complete and the electricity can flow round the circuit.
A circuit with a switch turned to the Off position or a circuit with any break is called?
a closed circuit
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
When the switch is closed it means that?
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
Can a switch in the off position cause electrical short circuit?
No, once the switch is turned off the circuit is de energized. A de energized circuit can not be shorted out to create a fault.
How does a circuit turn a switch on and off?
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
Why do the electrical gadgets stop working when switch is turned off?
A switch breaks the flow of electrons (current).
