Question

which of the following has low resistivity

• A. copper
• B. silver
• C. manganin
• D. constantan

Answer 1

The correct option is B

silver

Resistivity:

1. Electrical resistance of a conductor with a unit cross-sectional area and length.
2. Resistivity, a material property, is useful in comparing different materials based on their ability to conduct electric currents.
3. Poor conductors have high resistivity.
4. Silver has the highest thermal conductivity while having the lowest resistivity.

Hence,Option(B) is correct.
