An electrical cable consists of 125 strands of fine wire, eachhaving 2.65 mohm resistance. The same potential difference isapplied between the ends of all the strands and results in a totalcurrent of 0.750 A. (a) What is the current in each strand?(b) What is the applied potential difference? (c) What is theresistance of the cable?
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.
