Two cylindrical conductors with equal cross-sections and different resistivites rho_(1) and rho_(2) are point end to end. Find the charge at the boundary of the conduction if a current I flows from conductor 1 to conductor 2

Assertion (A): A conductor has + 3.2 xx 10^(-19) C charge. Reason (R): Conductor has gained 2 electrons.

The current flowing through a conductor is 2 mA at 50 V and 3 mA at 60 v. Is it an ohmic or non-ohmic conductor ?

The current flowing through a conductor is 2 mA at 50V and 3 mA at 60V. Is it an ohmic or nonohmic conductor ?

When a 40 Vm^(-1) - electric field is produced inside a conductor then 2xx10^(4) Am^(-2) ? current density is established in it. Resistivity of the conductor is

At the tempearture 0^(@) C the electric resistance of conductor 2 is eta times that of conductor 1. Thier temperatures coeficients of resistance are equal to alpha_(2) and alpha_(1) respectively. Find the tempearture coefficient of resistance of a circuit segment consisting of these two conductors when they are connected (a) In series , (b) In parallel .
