A wire of length L has resistance R. If the wire is now cut into three equal length pieces length pieces and attached to each other in parallel, the total resistance of the wire is now O R/9 O R/8 O R/3 O RI6 O R/2 O 9R OR O 2R O 8R O 6R O 4R O RI4 O 3R
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.
Assume a wire if length L and resistance R.
Since the resistance is directly proportional to the length,
Hence, when the wire is divided into three equal pieces , then resistance of each wire will be one-third of resistance of original wire.
