Consider a resistor of resistivity 4.12 × 10-8 Ω • m. If an electric field of 19 V/m is applied across the resistor and the electron volume concetration in the conductor is 5.82 × 1028 per m3, determine the drift velocity, in mm/s, of the free electron constituting the current.
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.
