Is there a symbol to identify a double insulated power tool?
A double insulated tool will have a picture of a box with a second box inside.
What is the function of a mains lead in a strip heater?
A mains lead is the power cable for the strip heater. The mains lead is single-insulated.
Do tree limbs affect power lines to the house?
Yes if the wires are of the non insulated type there will be a leakage to earth, contact your power company. Get expert help, do not attempt to cut trees that touch power lines it could be fatal.
What safety precautions apply to trailing power leads?
For safety precautions trailing power leads should be individually capped off. This can be done using a plastic tape designed especially for electrical wires or a permanent plastic cap.
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
Is there a symbol to identify a double insulated power tool?
A double insulated tool will have a picture of a box with a second box inside.
Why transformer core cuts thin sheet?
Transformer cores are made up of insulated laminations to cut down on eddy currents induced in the core, which is an unwanted power-loss.
What is a double insulated power tool?
inside a power tool is a roll of copper that is covered in a very thin layer of plastic to stop the machine from breaking down if too much dust builds up on it,double insulated means that there is two layers of plastic on the copper to increase the life of the toolClass II or double insulated tool is one which has been designed in such a way that it does not require a safety connection to ground.It is for safety not dust
What is the difference between insulated wire and ordinary cable?
Insulated wires and cables are commonly used conductors in power engineering
What is stacking factor of magnetic cores?
Magnetic cores are made up of thin ,lightly insulated ( coating of varnish ) laminatians to produce power loss in cores due to eddy current phenomenon . as a result ,the net cross sectin area of the core occupied by the magnetic material is less than its grosss cross section ; their ratio ( less than unity ) is known as stacking factor . depending upon the thicknesss of lamination ,stacking factor vary from 0.5 to 0.95 approching unity asthe lamination thickness increase
What do you look for in a processer for a computer?
The amount of cores, the power (Ghz), and the amount of power used (Watts)
From where can you buy power leads?
One can buy power leads online by searching the desired power lead you want to purchase. One can also buy power leads by going to any electronic store such as Best Buy and asking the employee "Where are (blank) power leads?"
Which does not state a principle related to why ground wires are in effective safety device?
Electronic devices are protected from power surges by having insulated wires
What is the difference of earth and insulated return in an electrical system?
An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.
Who is the bad guy in dragon universe?
The Alliance(Faction) is the bad guy the dragons(Predarvors) are the good guys at least until the dragon riders showed up after that no ones a good or a bad guy. Don`t even think about changing this because the Alliance waste the power cores that the dragons need to be born the Alliance have more power cores that they need to power Earth but waste them. The power cores are actually a part of the dragons.
Are electrical cords and cable wires for computers TV cable boxes insulated?
Yes, of course they are insulated. If they were not the signals would short out and be unusable. If electric power cords were not insulated they would short out and blow the breaker (or worse start a fire)!
Are overhead power lines insulated?
Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.
