A network of four resistances is connected to

9 \mathrm{~V}

battery, as shown in figure. The magnitude of voltage difference between the points

\mathrm{A}

and

\mathrm{B}

is __________

V

.

Accepted Answer

In the circuit

I=\frac{9}{3}=3 \mathrm{~A}

\mathrm{V}_{\mathrm{C}}-\mathrm{V}_{\mathrm{A}}=2 \times 1.5=3~~......(I)

\mathrm{V}_{\mathrm{C}}-\mathrm{V}_{\mathrm{B}}=4 \times 1.5=6~~......(II)

\mathrm{Eq}^{\mathrm{n}}(\mathrm{II})-\mathrm{Eq}^{\mathrm{n}}(\mathrm{I})

\mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}=6-3=3 \text { Volt }
