The current flowing through the circuit will be ?​

Answer 1

`</p><p>R_1=20\Omega \\</p><p>R_2=30\Omega \\</p><p>R_3=30\Omega \\</p><p>U=2V \\ \\</p><p>R_(12)=(1)/(R_1)+(1)/(R_2)=(R_1R_2)/(R_1+R_2)=15\Omega \\</p><p>R_(123)=(R_(12)R_3)/(R_(12)+R_3)=10\Omega \\</p><p>I=(U)/(R_(123))=\boxed{0.2A}</p><p>`

Hope this helps.
