When the cross-sectional area of a conducting wire is doubled while its length is cut in half, the resistance of the wire will be __________ . a. three time sits original value. b. one-third of its original value. c. the same as before. d. one-fourth of its original value. e. four times its original value.
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.
