piece of copper wire has a resistance of 1.5Ω. Solve for the resistance of the manganin wire of one-fourth length and one-fifth diameter if the resistivity of manganin is 20 times that of copper
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.
