Question

State the factors on which the strength of the electric current flowing in a given conductor depends.

Answer 1

Hint: A flow of particles is known as the electric current. It is also defined as the rate of flow of charge.
The flow of current is measured using the ammeter.
We can measure the electric current using ampere units.
The ampere is defined that the number of charge carriers moved through the wire per second.

Complete answer:
The maximum voltage experienced by the insulator after losing its insulating property is known as the electric strength.
We generally know that ohm’s law which states that, “ The current through the conductor between the two points is directly proportional to the voltage across the two points.
Thus we can write the formula as,
\[V = \dfrac{I}{R}\]
The strength of the electric current depends on the following factors they are, Conductor resistance and its cross-section. Conductor thickness and the material used to make conductor. The potential difference across the two points of the conductor.
Electrons drift velocity and its number density.
The current flow gets increased when we increased the temperature of the conductor.
Finally, the conductor’s electric current strength fully depends on the two factors they are, the resistance of the wire. Hence the resistance depends on the conductor length.
And another factor is the potential difference between the two points.

Note:
The steam of charged particles is known as the electric current.
Generally, the electric current creates the magnetic fields which we can use in the generators and motors.
The electromagnetic waves are emitted by the time-varying electric currents.
These electromagnetic waves are useful for the antenna communication
