Four resistors $40 \Omega, 60 \Omega, 90 \Omega$ and $110 \Omega$ are connected to a battery of emf 4 volt and negligible internal resistance as shown in the following figure. Then, the potential difference between the points $B$ and $D$ is $\varepsilon=40$ volt, $r=0 \Omega$ (a) $-0.2$ volt (b) $+0.2$ volt (c) $+1$ volt (d) $-1$ volt
In the circuit shown in Fig. 14.46, $E, F, G, H$ are cells of EMF $2,1,3$, and $1 \mathrm{~V}$, respectively, and their internal resistances are $2,1,3$, and $1 \Omega$, respectively. The potential difference between $D$ and $B$ is (A) $\frac{10}{13} \mathrm{~V}$ (B) $\frac{12}{13} \mathrm{~V}$ (C) $\frac{13}{13} \mathrm{~V}$ (D) $\frac{14}{13} \mathrm{~V}$
Four resistors are connected as shown in the following figure. A $6 \mathrm{~V}$ battery of negligible resistance is connected across terminals $A$ and $C$. The potential difference across terminals $B$ and $D$ will be (a) 0 volt (b) $1.5$ volt (c) 2 volt (d) 3 volt
