A high-voltage transmission line with a diameter of 2.00 cm and a length of 200 km carries a steady currentof 1 000 A. If the conductor is copper wire with a freecharge density of 8.46 ×1028 electrons/m3, over whattime interval does one electron travel the full length of the line?
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.
