What could cause voltage in a coil that has no current running through it?
A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage <<>> Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
How do you increase the current produced by coils?
to increase the turn of the coil ANSWER: Nobody can increase the current of a coil it actually losses power because of IR drop. from the source to the final output will always be less unless the current is amplified by an active device like a current amplifier where the power is from another source.
How does back emf affect starter motors?
Actually when the permanent coil dc motor rotates in magnet field by providing current an emf is induced in coil in the opposite direction of current in the coil by faraway law. this result in a torque in opposite direction. for example he the applied voltage is 10volts and the resistance is 10ohms theories current would be 10A. it is at time is zero it means when the switched is just on or circuit is just closed. if the induced emf is 10volts them the effective voltage will be 90volts. now he we calculate the current by ohms law the current will be 9A. This shows that at time is equal to zero the naughty current is passing through coil as the time pass amount of current passing through the coil will become less or minimum. As current and force are direct related the torque will become minimum. here the angular acceleration is decreasing it is not retarded. -:D
Why input current of USis less than Output current?
Why input current of USis less than Output current?
How does a speaker work in a circuit?
They will either pull in or push out depending on the polarity of the DC voltage and remain stationary. This is a bad idea as the DC resistance of the voice coil is much less than the AC impedance of the voice coil and it is possible to overheat and burn out the voice coil due to the much higher current the DC voltage can produce in the voice coil compared to the AC voltage that would drive the voice coil in normal operation.

What is choke coil?
A choke coil is an inductor, which is designed to block a particular frequency in an electrical circuit while passing signals of very less frequency or direct current.
Why heater coil glow but supply wire not glow?
Heater coil is made of alloys such as meganin wire ,and is having high melting point .Alloys have high resistance due to which most of electrical energy is converted into heat energy.According to joules law of heating heat produced in a conductor is directly propotional to square of current and is directly proptional to resistance of conductor and time for which current flows.Heater wire does not glow because of having less resistance

Does current change in a circuit having bulb in series with a resistance?
Absolutely the more Resistance is put in series the less current Will flow.

How could you identify the less coil number side of a transformer?
By measuring its resistance with an accurate multimeter provided the coil is not blown. If less resistance compared to that of the other coil would decide that it is less number turn.
How does a car coil work?
An ignition coil is two loops or "Coils" of wire one inside the other. When you apply a current to the Coil of wire with less coils of wire it creates a magnetic Field. When the magnetic Field collapses when the electricity is removed this induces a current in both coils of wire. The coil that has just had the power removed from to a very small degree. To the other coil that has many more coils of wire the current induced is very high voltage. This causes the spark to jump the gap on the spark plug. To make this happen correctly the power must be turn on and of very quickly and cleanly.
A step up transformer has 300 turns on its primary coil and 90 000 turns on its secondary coil If the current flowing through the secondary is .5 amps What is the current flowing in the primary?
1500A. You probably have pri / secondary confused. primary is usually used to denote the higher voltage winding, which will have more turns than the secondary. The secondary will have lower voltage, less turns, but will carry more current.
How do you make a permanent magnet lose its magnetism?
Heat allows the atoms in a magnet to become less organized, causing the individual magnetic fields of the atoms to cancel each other out, dissipating the effect.An electromagnet is simply a wire coil energized by an electric current, which aligns its atoms (polarize them) as electrons flow through it, creating a temporary magnetic field.AnswerThe most effective way of demagnetising a magnet is to insert it into a coil, pass an a.c. current through the coil and gradually reduce that current to zero.
How can the strength of an electromagnet be increased or decreased?
the current from the battery controls the strength of the electromagnet. Adjusting the voltage will also adjust the current as will adjusting the resistance in accordance with Ohm's Law. Current= voltage/resistance
What is hypo-tonics?
it means having a lower osmotic pressure then a camparison solution! It also means Having less than normal tone or tension, as of muscles or arteries.
