Kirchoff's first law, i.e., $$\sum    i = 0$$ at a junction, deals with the conservation of

In series combination of resistances:

What steady current can be drawn from an accumulator of capacity $$80\ Ah$$?

At temperature $$0 K,$$  the germanium behaves as a/an

Constantan wire is used for making standard resistance, because it has

Which physical quantity cannot be determined with the help of potentiometer?

Two non ideal batteries are connected in series. Consider the following statements
(A) The equivalent emf is larger than either of the two emfs.
(B) The equivalent internal resistance is smaller than either of the two internal resistances.

When potential difference is applied across an electrolyte, then Ohm's law is obeyed at

The smallest resistance that can be obtained by the combination of  $$n$$ resistors, each of resistance  $$R$$ is:

Potentiometer measures potential more accurately because
