Two wires (copper and aluminium) have equal area of cross section and have same resistance. Which one is longer ?
Answers
Answer:
Copper wire is longer than aluminium.
Explanation:
Since aluminium have greater resistance so in order to make the copper wire's resistance same as of aluminium it must get longer.
Copper is longer than aluminium.
Explanation:
Copper is considered as the longer wire when compared to the aluminium for the following reasons.
- There is a lower specific electrical resistivity towards copper than that of aluminium.
- And the copper has also a lower Coefficient towards thermal expansion.
- The copper does not have any issue over the corrosion.
- When compared to aluminium to Copper shows a very good resistance in order to Creep.
Copper is considered as one of the easiest metals to sell and it has the highest specific weight that does not react with water.
This copper wire is available even in the lower cross section and it is easy to install and repair.
