Why does the magnetization current impose on upper limit on the voltage applied to a transformer core?
The magnetization current imposes an upper limit on the voltage applied to a transformer core due to the ability of the respective spark gap to extinguish. If too much current supply is available the spark gap becomes overheated. This makes it unable to "switch-off" when the high or elevated supply current is flowing through it.
Why inductor is only used for ac power supply?
Because inductance is only related to alternating current. Direct current doesn't induce eletrical current on a secondary coil placed on a primary coil, because there is no frequency generated by direct current, and all you get is a single electrical current flowing through the wire without interfering with a coil placed near to the primary coil. What makes all the difference is the cycles per second that only alternating current can generate.
What is the effect of inductor you rectifier?
it makes current wave more smooth
Explain Why it is important that the current in the coil of a motor changes direction every time the coil makes a half revulotion?
due to commutation the current in the coil reverses
What is the difference between an short circuit and a closed circuit?
You know there is a differnce. The dynamic short circuit is dynamic and the static short circuit is static. It's common sense really.dyanamic means when due to some external source theresistance becomes zero ,can be through anythin due to high supply of current or anything,the current in that circiut becomes infinite and that result s in short circuiting. Static short circuit means when through the different changes in the voltage makes the resistance zero and current infinite , V = I/R WHERE R= 0 AND CURRENT BECOMES INFINIT AND THAT RESULT IN A SHORT CIRCUIT
Which property makes it difficult for electricity to pass through a material?
density
Is inertia the property of matter that makes it difficult to push a stopped car?
Inertia
What property makes certain metalloids useful as switches to turn on a small electric current on and off?
any property
What The property of a coil that makes it resist changes in current is called?

How can you protect your house or car from a lien holder?
The person has a lien because they have a legal financial interest in the property. That makes 'protecting' the property very difficult without either purchasing their interest from them or having their interest removed through bankruptcy.
What a moving magnet makes?
makes current flow through a magnet
What component that makes it more difficult for current to flow?
IF there is a Resistor
What property makes semimetals useful as switches to turn a small elecric current on the off?
The property that makes semi-metals useful as "switches" is that their varying ability to conduct electricity.
