There is no one formula to guide construction of a coil used in a DC application. There are far too many different ones, and each has special considerations. Is the coil being used in an automobile to fire the spark plugs? Or in the solenoid to release the trunk lid of said automobile?
What else can I help you with?
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Can a 12vac coil be operated by 24vdc?
no, in an ac circuit the coil provides impedance but the DC coil needs some resistance to limit the current
What is DC generator and a moving coil galvanometer?
A DC generator is an electrical device that converts mechanical energy into direct current (DC) electrical energy through electromagnetic induction. It consists of a rotating coil within a magnetic field, which induces a voltage as the coil spins. A moving coil galvanometer, on the other hand, is an instrument used to measure small electric currents by detecting the angular displacement of a coil suspended in a magnetic field. The deflection of the coil is proportional to the current flowing through it, allowing for precise measurements.
What is the formula to calculate beta DC?
beta dc= ic/ib!!
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.
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Ac to DC formula?
formula for ac to dc
What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.
What is the difference between 10 amp and 15 amp?
what is the diference between 12V 15A DC coil & 12V 10 amps DC coil
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
What is moving coil voltmeter?
mic or moving iron coil is instrument type works on ac and dc

What will happen if you take a dc coil off its armature?
It will no longer be attached!
How do you connect a diode across a ac coil?
You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.
What is the formula to calculate beta DC?
beta dc= ic/ib!!
