Find the equvalent resistance of the metwork shown in figure between the point A and B.

Text Solution

Verified by Experts

The 10(Omega) resistor and the 30(Omega) resistor are connected in parallel. The equivalent resistance between A and C is
`R_(1)=((10(Omega))(30(Omega)))/(10(Omega)+30(Omega))=7.5(Omega)`.
`This is connected with 2.5(Omega)in series. The equivalent resistance between A and B is`7.5(Omega)=2.5(Omega)=10(Omega)=10(Omega).`
