Two cells of emfs 1.5 V and 2.0V internall resistance `2 Omega` and `1 Omega` respectively have their negative terminals joined by a wire of `6 Omega` and positive terminals by another wire of `4 Omega`. A third wire of `8 Omega` connects the mid points of these two wires. Find the current through `8 Omega` and the potential difference at the ends of the third wire.
