Ramesh uses six bulbs B1, B2, B3, B4, B5 and B6 to make a circuit that is similar to a domestic circuit, as shown in the figure. He shows this circuit to his teacher. His teacher tells him that the circuit constructed by him can exactly replicate a domestic curcuit if he removes one bulb from the same. Which two bulb should be removed from the circuit by Ramesh to make it similar to a domestic electric circuit?
