4) A copper wire has a diameter of 1.60mm and carrier a current of 2.5A. Given the density of free electron is 8.5*1028 electron per cubic meter and Pcopper is 1.72*10-8 ohm.m 1)current density of the wire 2)drift velocity 3) resistance of the copper wire that has length of 3.0m
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
