Anil Ahlawat Solutions for Chapter: Electricity, Exercise 2: EXERCISES

The resistors $R_1, R_2, R_3$ and $R_4$ in the given circuit are all equal in value and connected with a negligible resistance wire. Which of the following is correct relationship between the voltmeters readings $V_1$, $V_2$ and $V_3$?

In the circuit shown here, the ammeter $\mathrm{A}$ reads $5 \mathrm{A}$ and the voltmeter V reads $20 \mathrm{V}$. The correct value of resistance $R$ is :

A ring is made of a wire having a resistance $12 \mathrm{\Omega }$. The points $P$ and $Q$ as shown in figure, at which a current carrying conductor should be connected, so that the resistance of the sub circuit between these Points is equal to $\frac{8}{3} \mathrm{\Omega }$, divide the ring in lengths $l_1$ and $l_2$ then :

Consider a thin square sheet of side $x$ and thickness $y$ made of a material of resistivity $\rho$. The resistance between two opposite faces, shown by the shaded areas in the figure is points is equal to :

The plot represents the flow of current through a wire at three different time intervals. The ratio of charges flowing through the wire at different intervals is :
