i have studied that a conductor is equipotential and charges don't flow through it but how does it flow through a wire?

I think you may be talking about a conductor in electrostatics.ajaysabarish said:and charges don't flow through it
but potential difference across a wire(conductor) is taken as zero while writing kirchhoffs law?so there is no potential difference hence charges shouldn't flow through itZapperZ said:It is because there is an external "source" that keeps one end of it at one potential, and the other end at another potential.
Note that the conductor does not have zero resistance for this to occur.

This means that if the conductor is not in electrostatic equilibrium, then there is a (net) electric field on the charged particles inside, and thus, a potential difference, which causes current.
iam talking about both,just comparing them.Dale said:I think you may be talking about a conductor in electrostatics.

yes,so shouldn't it have a resistance,but why don't we take it during kirchhoffs lawZapperZ said:Try doing Kirchoff law on such a circuit, i.e. with a zero-resistance conductor connecting the ends of a battery. You will have a SHORT!

Current refers to the flow of electric charge through a conductor, while electricity is a form of energy that results from the movement of charged particles.
Current is measured in units of amperes (A), with 1 ampere being equivalent to 1 coulomb of charge passing through a point in 1 second.
The flow of current is affected by the resistance of the material, the voltage applied, and the temperature of the conductor.
Ohm's Law states that the current through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. This means that as voltage increases, current also increases, but as resistance increases, current decreases.
Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically. AC is the type of current used in most household and industrial electricity, while DC is commonly used in batteries and electronic devices.
