Question 259: Current Electricity

Question

Consider four conducting materials copper,
tungsten, mercury and aluminium with
resistivity $$\rho $$C, $$\rho $$T, $$\rho $$M and $$\rho $$A respectively. Then :

C

Answer

$$\rho $$C >  $$\rho $$A >  $$\rho $$T

Answer

$$\rho $$M >  $$\rho $$A >  $$\rho $$C

Answer

$$\rho $$A >  $$\rho $$T >  $$\rho $$C

Answer

$$\rho $$A >  $$\rho $$M >  $$\rho $$C
