A student wants to know how much current passes through three (3) wires that are made of different materials (copper, germanium, and hard rubber) when a voltage of 1.0 V is applied to each of them, given that they all have the same radius of 1.5cm and length of 1.0 m. (a) Calculate the currents passing through each wire. (b) Using the calculated currents, what can you say about the three materials with regards to their use in the electrical industry? Hint: How is rubber used in the electrical industry?
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.
