What are the functions of a switch?
The function of a switch is to open or close a path for electricity.
A circuit flow on a open switch?
no because when you close it, the circuit is complete so it lets the electrons pass through
How does an eletrical switch work?
it's basically a gate that you can open and close to let electricity through or not thud allowing a connection or breaking one.
How does a switch control the flow of electricity?
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
What are the function of switches?
The function of a switch is to open or close a path for electricity.
Why does the light turn on as soon as you flip the lightswitch?
The light is connected in a electrical circuit. The electricity will only pass through the circuit if the circuit is closed. A switch can open and close this circuit by simply not making contact with the next wire so the electricity can not be passed on. When you turn on the switch, the circuit gets closed again and the electricity will run through, so to the light. Because electricity has the speed of light (+-300 000 km/h) it will seems like the electricity reaches the light immediately. Plus the neutral travels through the filement of the bulb and down the switch wire giving an instant closed circuit when switch is closed
Give two possible reasons why their circuit does not work when they close the switch?
The cell has no more electricity and the bulb has blown.
How can one close an open circuit?
One can close an open circuit by adding a complete loop of wire. This will allow the electricity to flow through the circuit, while electricity will not flow in an open circuit.
How can you make a 12 volt fence controller for an electric fence?
A 12 volt fence controller is basically a pulsed transformer. It is run through a long wire. The long wire acts as a resistor. You could rig up an electromagnet as some sort of switch. When the electricity is off, the magnet would close the switch running power through the transformer. That would open the switch cutting off power to the transformer. Electricity running through the wire can paralyze animals include animals called humans. The pulse is unpleasant. The time electricity is not running through the wire allows them to pull away from the fence. that way you do not walk along the fence and find dead animals and humans alongside the fence.
Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
Is it possible to get a digital or electronic compass that is not affected by steel structures in its close vicinity?
No compass can be accurate with steel structures in close vicinity but a GPS will do the trick
Why does a fridge light turn off when you close it?
A switch is fitted to turn off the light whilst the door is closed to avoid wasting electricity and money.
