To answer this question, let's look at the definition of the following words.
Voltage, Current, and Resistance
One volt is one joule of energy per coulomb of electrons. One ampere means one coulomb of electrons is moving through the wire each second.
R = V ÷ I = J/s ÷ C/s = J/C
The resistance measures the amount of energy that is required to make one coulomb of electrons move through the wire. The charge of one electron is 1.6 * 10^-19 C. To determine the number of electrons per coulomb, invert this number.
Number of electrons per coulomb = 6.25 * 10^18
One ampere means 6.25 * 10^18 electrons are moving through the wire and resistor each second. If the resistor is one ohm, one volt will be required for this to happen. To determine the amount of charge that is moving in a wire each second, you will need to wire's resistance and the voltage that is being used. Voltage and resistance determine the amount of charge that is moving through the wire each second. I hope this answers your question.

Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
What effect does increasing the current have on solenoid?
it will produce a stronger magnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
What are the conditions necessary for a terrestrial planet to have a strong magnetic field?
both a molten metallic core and reasonably fast rotation
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
What will a moving magnetic field produce?
I think it will produce electricity.
Every moving charge can produce a field?
magnetic field
Does light produce both electric and magnetic field?
light exhibit magnetic field but i cant say about electric Field...
How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
Can a changing magnetic field produce a steady electric field?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
How do electric generators produce a current?
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
