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.

What causes electrons to flow when a switch is turned on?
When a switch is turned on, it creates a closed circuit that allows electrons to flow from the negative terminal of the power source to the positive terminal. This flow of electrons is driven by the electric field created by the voltage difference between the two terminals.
What causes electrons to flow when a switch is truned on?
When a switch is turned on, it creates a complete circuit that allows electrons to flow. The potential difference (voltage) provided by the power source pushes the electrons through the circuit, causing them to move from the negative terminal to the positive terminal. The flow of electrons creates an electric current that powers electrical devices connected in the circuit.
What happens to an electric current at a switch?
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
Which insulator does a switch use to cut off the current in a circuit?
A switch uses an insulator called an "air gap" to cut off the current flow in a circuit. When the switch is turned off, it creates a physical break in the circuit, preventing electricity from passing through.
How does a torch work-circuit?
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

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 causes electrons flow when a 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.
What happens to an electric current at a switch?
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
What are the basic principles of switch wiring?
The basic principles of switch wiring involve connecting the switch to the power source and the light fixture in a circuit. When the switch is turned on, it completes the circuit and allows electricity to flow to the light, turning it on. When the switch is turned off, it breaks the circuit, stopping the flow of electricity and turning off the light.
What is the purpose of the neutral wire in a light switch circuit that allows the flow of electricity to be completed when the switch is turned on?
The purpose of the neutral wire in a light switch circuit is to provide a return path for the electricity to flow back to the power source once the switch is turned on, completing the circuit and allowing the light to turn on.
