In the given circuit,the total power loss is $10 \text{ W}$. Find the value of resistance $R$ in $\Omega$.

The resistances in the following circuit are $R_1 = R_2 = R_3 = 6.0 \ \Omega$. The emf of the battery is $12 \ V$. When switch $S$ is closed, the potential across resistance $R_1$ changes by an amount:

$A$ silver voltameter of resistance $2\, \Omega$ and a $3\, \Omega$ resistor are connected in series across a cell. If a resistance of $2\, \Omega$ is connected in parallel with the voltameter, then the rate of deposition of silver

In the given circuit,for maximum power to be transferred from a battery with an internal resistance of $4\, \Omega$,what should be the value of $R$ in $\Omega$?

Refer to the circuit shown. What will be the total power dissipation in the circuit if $P$ is the power dissipated in $R_1$ (in $P$)? It is given that $R_2 = 4 R_1$ and $R_3 = 12 R_1$.

In the circuit shown below,the current that flows from $a$ to $b$ when the switch $S$ is closed is ............... $A$.
