Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
Mobility $ \mu = \frac{v}{E} = \frac{m/s}{V/m} = m^2 V^{-1}s^{-1}$
Current density $ J = \frac{I}{A} = Am^{-2}$
Resistivity $ \rho = \frac{R.A}{l} = \Omega m$
Conductivity $\sigma = \frac{1}{\rho}= \Omega^{-1}m^{-1}$
