$n$ identical cells each of electromotive force $e$ and internal resistance $r$ are connected in series of this combination. The current through $V$ is:

In the given graphs which is the graph depicting Ohm's Law ?

A resistor of $6\Omega$ is connected in series with another resistor of $4 \Omega$. A potential difference of $20 \ V$ is applied across the combination. Calculate the current in the circuit.

Three resistances $R_1,R_2$ & $R_3$ $(R_1> R_2> R_3)$ are connected in series. If current $I_1,I_2$ & $I_3$ respectively is flowing through them, the correct relation will be
