A piece of material with a square cross-section measuring 1 mm on each side has a length of 1 m. What is the resistance of this material if it were made of aluminium? Fused quartz? Finally, calculate the current through each piece of material if a potential difference of 1 volt is applied over its length.
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.
