That means it doesn't change over time.

When a conducting loop moves through a constant magnetic field, it induces an electric current within the loop. This is due to the phenomenon of electromagnetic induction, where the changing magnetic field creates an electric field that drives the flow of electrons in the loop, generating an electric current.
40 A -providing the voltage remains constant.
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
Since V=IR then the answer would be voltage and/or resistance.AnswerIn the equation, V = IR, resistance is a constant -so it does not change with a change in current.
The biggest unit of electric charge is the coulomb (C), which is equivalent to the charge transported by a constant current of one ampere in one second.
Here are a couple. Assuming everything is "normal" here, if you drop a bagel in the toaster and turn it on by pushing the lever down, the AC current the toaster uses (draws) will stabilize after a few seconds and stay constant. If you turn on your car's headlights, each lamp will draw a constant current from the DC source after a few seconds of "warm up" time. Those are examples of constant electric current.
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is due to the movement of charged particles, such as electrons, which generate a magnetic field. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.
Some disadvantages of electric current include the risk of electric shock, potential fire hazards due to overheating, and the need for constant monitoring and maintenance of electrical systems. Additionally, reliance on electric current can also lead to increased electricity bills and environmental concerns related to energy generation.
