List of top Physics Questions on Conductance asked in MET

The electric resistance of a wire is \( R \). If the length of the wire is increased to double by stretching it, then the new resistance of the wire is

When a force \(F_1\) acts on a particle, frequency is 6 Hz and when a force \(F_2\) acts, frequency is 8 Hz. What is the frequency when both the forces act simultaneously in same direction?

At what temperature will the resistance of a copper wire become three times its value at 0°C? (Temperature coefficient of resistance for copper \( \alpha = 4 \times 10^{-3} /°C \))

The incorrect statement in respect of chromyl chloride test is

A wire of resistance $R$ is stretched to double its length. Its new resistance will be:
