nce of 0.49 Ω at 20.0°C, and an iron wire has a resistance of 0.57 Ω at the same temperature. a) At what temperature, in degrees Celsius, are their resistances equal? The temperature coefficient of copper is 3.9 * 10^-3 (degrees Celsius)^-1, while t
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.
A copper wire has a resistance of 0.49 Ω at 20.0°C, and an iron wire has a resistance of 0.57 Ω at the same temperature.
a) At what temperature, in degrees Celsius, are their resistances equal? The temperature coefficient of copper is 3.9 * 10^-3 (degrees Celsius)^-1, while that for iron is 5.0 * 10^-3 (degrees Celsius)^-1.
We know that we have given that the A copper wire has a resistance of 0.49 Ω at 20.0°C, and an iron wire has a resistance of 0.57 Ω at the same temperature.
let the resistance of the copper wire is R1 and temperature T1 = 20oC
The resistance of the iron wire is R2 at the same temperature T1= 20oC
Now We know that the formula of the resistance in terms of the temperature
