The product of counductivity and resistivity of a conductor
Options
- Adepends on pressure applied
- Bdepends on current flowing through conductor
- Cis the same for all conductors
- Dvaries from conductor to conductor
Correct answer
C. is the same for all conductors
Step-by-step solution
Conductivity ( ) is the reciprocal of resistivity. i.e., = 1
