The electric current $i$ in the circuit shown is (in $\text{ A}$)

For the circuit shown,with $R_1 = 1.0\,\Omega$,$R_2 = 2.0\,\Omega$,$E_1 = 2\,V$ and $E_2 = E_3 = 4\,V$,the potential difference between the points $a$ and $b$ is approximately (in $V$):

In the given figure,the ratio of current in the $8\,\Omega$ resistor to the current in the $3\,\Omega$ resistor will be:

For the circuit shown in the figure,the current $I$ will be .......$A$.

In the circuit,the galvanometer $G$ shows zero deflection. If the internal resistance of batteries $A$ and $B$ is negligible,then the value of resistance $R$ is ....... $\Omega$.

In the circuit shown below,the resistance of the galvanometer is $20 \, \Omega$. In which of the following alternatives are the currents arranged strictly in decreasing order?
