If the resistance of pure iron is 0.10 Ω at 20oC and the temperature coefficient of iron is 5.0 x 10-3 oC-1, calculate i) the resistance of pure iron at 80oC. ii) power consumed in resistor if the current flow through it is 13 A.
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.
If the resistance of pure iron is 0.10 Ω at 20oC and the temperature coefficient of iron is 5.0 x 10-3 oC-1, calculate
i) the resistance of pure iron at 80oC.
