1- Lay an aluminum strip 10 cm long, 2 cm wide and and 3 mm thick. A current flows in the longitudinal direction and a field of 0.75 T is perpendicular to the blade. If the potential between the two long sides of the blade is 3 micro-Volt, what is the current flowing through the blade?
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.
