In the given circuit, diode \mathrm{D_{1}} is reverse biased, so it will not conduct. Diodes \mathrm{D_{2}} and \mathrm{D_{3}} are forward biased,

so they will conduct. The corresponding equivalent circuit is a shown in the figure.

The equivalent resistnce of the circuit is

\mathrm{R_{e q}=\frac{(5+5) \times 20}{(5+5)+20}=\frac{10 \times 20}{10+20}=\frac{200}{30}=\frac{20}{3} \Omega}

Current through the battery, \mathrm{\mathrm{I}=\frac{10 \mathrm{~V}}{\frac{20}{3} \Omega}=1.5 \mathrm{~A}}
