The effective resistance between $P$ and $Q$ for the following network is

Five identical resistors each of resistance $R=1500 \Omega$ are connected to a $300 \mathrm{V}$ battery as shown in the circuit. The reading of the ideal ammeter $A$ is

Consider the circuit shown. 

If all the cells have negligible internal resistance, what will be the current through the $2 \mathrm{\Omega }$ resistor when steady state is reached?

The four arms of a Wheatstone bridge have resistances as shown in the figure. A galvanometer of $15\Omega$ resistance is connected across BD. Calculate the current through the galvanometer when a potential difference of $10 \mathrm{V}$ is maintained across AC.
