If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
How does a change over switch works?
When the supply from GEB is cut away, at that time the consumer is required to change over from the main supply to the private generator, so that he cut the supply from mains and switches to Generator with a change over switch.
Is power proportional to voltage squared?
Yes, power is directly proportional to current. Power is equal to amps times volts, and as current goes up (with voltage remaining constant), power will go up. Double current, and you'll double power. Cut current in half, and you'll cut power in half. (Voltage stays the same in all this).
How does a double-walled glass container cut down on heat loss?
It is like double glazing. An extra layer of gas or a vacuum in between will act as a very good insulator, helping to minimise heat flow.
How does the tubelight on a vendor's cart work?
a short circuit is brought about when short cut is provided for the current flowing there a as a result current bulb up the dangerous the electro-magnet coils are clus wonder and there is a chance of short circuit hence wire is to be inssulated so no electric currrent stops across and no short curict will be produced
What is an RCD cut the current to a circuit?
RCD cut the current to the circuit while preventing the electric shock
A break in the wires of an electric current will the circuit and the current?
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
How do you cut an electric socket safely?
If you are not talking literally about cutting a socket and are referring about the sockets circuit, then all that needs to happen is, a switch needs to be cut into the circuit.
Can a single pole switch replace a starter in a tube light?
No. Starter comes in the circuit initially and then cuts off once the tube is on. If you use the switch, it wont be cut off automatically. If you want to use the switch manually then it technically possible to do so
What is the difference between an open and closed circuit in hydraulic circuit?
In an open circuit, the circuit doesn't power the load because it isn't closed fully. A closed circuit closes properly and can power the load. If you didn't know, the load is the thing your trying to power.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
How do circuit breakers keep the wires in an electrical circuit from over heating?
Because the amount of heating depends on how much current is in the wires. So you set the CB to cut the current if it exceeds the rated current for that wire.
Why is thermal switch often included on the control circuit for a glow-coil pilot burner ignition?
Thermal switch is to cut off the pilot ignition circuit when the heater temperature is beyond a set temperature. The thermal switch limits the temperature and protects the heaters

How does a touch lamp work?
A membrane switch is an electrical switch for turning a circuit off and on. It is used as user-interface for computers. Many people use it without even knowing they do.
