In the given figure,each plate of the capacitor with capacitance $C$ has a charge. Find the charge on the capacitor.

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

$A$ torch battery consists of two cells of $1.45\,V$ and an internal resistance of $0.15\,\Omega$ each. Both cells send current through the filament of a lamp having a resistance of $1.5\,\Omega$. The value of the current will be ....... $A$.

In the circuit shown below,if the potential at point $A$ is taken to be zero,the potential at point $B$ is .............. $V$.

Two resistances of $400 \Omega$ and $800 \Omega$ are connected in series with a $6 \text{ V}$ battery of negligible internal resistance. $A$ voltmeter of resistance $10000 \Omega$ is used to measure the potential difference across the $400 \Omega$ resistor. The error in the measurement of potential difference in volts is approximately:

$A$ battery of $emf$ $10\,V$ is connected to resistances as shown in the figure. The potential difference between $A$ and $B$,$(V_A - V_B)$ is ................ $V$.
