Why alternating current cannot be stored in battery?
Batteries store electrical energy in the form of chemical energy. Alternating current (AC) constantly changes direction, which makes it unsuitable for direct storage in a battery, which requires a constant flow of electrons in one direction to charge. However, AC can be converted to direct current (DC) before being stored in a battery.
Why is the freezer the coldest in the refrigerator?
the freezer serves a very important role in our society without it food losses would be off the charts border line ludicrous... it makes sure the foods we are not going to be eating for a while stays good... freezeing it in time... so that we may eat it in the distant future... and because the refrigerator part doesnt get cold enough to freeze anything
What makes a magnet stick to a refrigerator?
A magnet sticks to a refrigerator because the metal of the fridge is ferromagnetic, meaning it can be magnetized. When a magnet is pressed against the fridge, it creates a magnetic field that aligns with the refrigerator's magnetic field, causing the two to stick together.
Why does a wire begin to vibrate when ac is passed through it?
When AC (alternating current) is passed through a wire, the current flow changes direction periodically. This change in current flow causes the wire to experience an electromagnetic force that makes it move back and forth, creating vibrations. These vibrations are more pronounced at certain frequencies because of resonance effects.
Why is the freezer at the top of a refrigerator instead of at the bottom?
Having the freezer at the top of the refrigerator allows cold air, which is denser and tends to sink, to flow into the refrigerator compartment more easily. This design also makes it more convenient to access frequently used items in the refrigerator.

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 do you call a person who makes charts?
Cartographer
What is meaning of cartographer?
One who makes charts or maps.
What makes a refrigerator a magnet?
The refrigerator isn't actually a magnet, it it simply made of metal which magnets can then stick to.
What does the compressor of a refrigerator do?
It makes noise and cools everything.
Why did the inventor name it refrigerator?
The name refrigerator is intended to mean that which makes things frigid (meaning very cold).
What is different amplifier and rectifier?
An amplifier makes a (generally larger) copy of a signal or voltage. A rectifier allows current to pass in only one direction.
Who makes Kenmore refrigerator model no 46 62154?
Amana
How the Coriolis effect work?
