In the following circuit composed of identical resistors,across which terminals would you connect a battery in order to dissipate energy in all resistors?

In the circuit given below,if the bulb is to glow with maximum intensity,the value of $R$ is (neglect internal resistance of the cell) (in $\Omega$)

In the circuit shown in the figure, if the ammeter and voltmeter are ideal, then the power consumed in the $9 \, \Omega$ resistor will be .......... $W$.

Assertion : In a simple battery circuit,the point of the lowest potential is the negative terminal of the battery.
Reason : The current flows towards the point of the higher potential,as it does in such a circuit from the negative to the positive terminal.

In the circuit,$R_{1} = R_{2} = R$. The value of $E$ and $R_{1}$ are $\ldots \ldots \ldots$ ($E$ = $EMF$,$R_{1}$ = resistance).

Find the current in the circuit. (in $ A$)
