How does a switch control an electric device?
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
Rupturing capacity of a circuit breaker?
the maximum short current that can be safely break by the circuit breaker.
What is the length of time that a motor can safely run on starting and full load current?
It depends on the insulation provided in winding, motor can safely run on full load current. and over that it may burn but depends on cooling system of the motor. Motor can burn if insulation fails, failure of insulation depends on only the temperature rise.
Why Short circuits cause fire?
Because a short allows/causes very large current flow, which "overloads" the wire [conductor]. When a conductor [wire] carries much more current than is safely capable, then the conductor heats up, and can cause enough heat to ignite the insulation and adjacent combustible materials on fire.
Why can't human beings sit safely on electric power lines?
Theoretically, human beings can sit safely on an individual overhead line conductor, providing no part of their body comes into contact with another conductor or the earth. In practise, of course, it's another story as it's highly improbable that anyone could approach a high-voltage line in the first place!
Does the gauge of a wire change the amount the energy it carries?
It determines the amount of electric current it can safely carry
What is the difference between electronic current and conventional current?
Difference between conventional current and electric current? • Electric current can be either negative or positive, but conventional current is always positive.• The conventional current for an electron flow is positive, whereas the electrical current is negative.• For a flow of positive charges, both the electric current and the conventional current are the same.• Since almost every electrical circuit uses an electron flow, it can be safely stated that the conventional current = - electrical current.• In conventional current, the flow of electrons is assumed as a flow of protons on the opposite direction.
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.
How long can you safely run an electric fan?
3 hours
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.

How can you increase your current height safely and effectively?
You can add up to 4 inches to your height safely and effectively. Visit http://www.heightsecrets.com
What type of fires can be put out safely with water?
The large majority of fires can be put out safely with water. The exceptions are electrical, grease, or some super heated metals.
What is the function of the wire gauge?
Wire gauge is a measurement of how large a wire is, either in diameter or cross sectional area. This determines the amount of electric current a wire can safely carry, as well as its electrical resistance and weight per unit of length.
Can you lose 10 pound safely?
it depends on your current weight, consult your doctor about how much you should lose, and then work out a plan to safely achieve your goals.
How can birds perch safely on an electric wire that would kill us?
They are not directly touching the ground. There is no way for the electrical current to complete itself if it went through the bird. If you were to stand on the ground and touch the wire you would be 'zapped', for you completed an alternate route for the electricity to take.
