Two conducting wires X and Y are made of copper-nickel and have equal lengths, but the resistance of wire X is three times greater than that of wire Y’s. What is the ratio of the radius of wire X to that of Y’s? Choices: √3:1, 1:1, 1:√3, 1:3,
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.
