A conducting device obeys ohm's law when the resistance of device is independent of the magnitude and polarity of the applied potential difference which happens in metallic conductors. Reason is false as ohm's law is not true for non-ohmic conductors such as junction diodes etc.

    Two batteries $V_1$ and $V_2$ are connected to three resistors as shown below. If $V_1=2 \,V$ and $V_2=0 \,V$, then the current $I=3 \,mA$. If $V_1=0 \,V$ and $V_2=4 \,V$, then the current $I=4 \,mA$. Now, if $V_1=10 \,V$ and $V_2=10 \,V$, then the current $I$ will be ............ $\,mA$
