A beam of doubly charged negative ions with a number density of 2.7 × 10^18 cm−3 is traveling north with a speed of 1.0 × 10^5 m/s. What are the (a) magnitude and (b) direction of the current density? The question states 2.7, however the solution is stating 2. This is incorrect. What is the correct solution?
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.
