The currents in different parts of the electric circuit are shown in the following figure. The value of current $i$ is (in $\text{ A}$)

In the following circuit,the current $I_3$ is

When the resistance $R$ (indicated in the figure below) is changed from $1 \, k\Omega$ to $10 \, k\Omega$,the current flowing through the resistance $R'$ does not change. What is the value of the resistor $R'$?

Five equal resistances are connected in a network as shown in the figure. The net resistance between the points $A$ and $B$ is

In the given circuit,the values of $I_1, I_2, I_3$ are respectively:

In the given figure: $V_1=V, V_2=\alpha V, R_1=\beta R, R_2=\gamma R$,where $\alpha, \beta$,and $\gamma$ are positive real numbers. The value of current $I$ is
