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.
What else can I help you with?
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
Every moving charge can produce a field?
Yes, a moving charge can produce a magnetic field as it generates a magnetic field due to its motion. This phenomenon is described by Ampere's law in electromagnetism.
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
What will a moving magnetic field produce?
I think it will produce electricity.
Why does the earth have a magnetic field when some planets don't?
The Earth's magnetic field is generated by a process called the dynamo effect, which is driven by the movement of molten iron and nickel in its outer core. Not all planets have the necessary conditions, such as a molten core and sufficient rotation, to generate a magnetic field.
What must happen in order electric charges to produce a magnetic field?
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
Will alternating current produce a magnetic field?
Yes, alternating current will produce a magnetic field due to the changing electric field it generates as it flows through a conductor. This magnetic field is essential for the operation of devices such as transformers and electric motors.
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.
Can electricity easily produce a magnetic field?
Yes, electricity can easily produce a magnetic field by running current through a conductor. The magnetic field strength is directly proportional to the amount of current flowing through the conductor.
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.
Why does a current carrying wire produce no magnetic field?
A current-carrying wire does produce a magnetic field around it according to Ampere's law, which states that a current generates a magnetic field. This phenomenon is the basis for the operation of electromagnets and the magnetic field produced is directly proportional the current flowing through the wire.
