(a) False

To make a battery of two cells, the negative terminal of one cell must be connected to the positive terminal of the other cell.

(b) True

The wire of the fuse is made of special material which has a low melting point. When large current passes through a fuse, it melts quickly and breaks the circuit.

(c) False

Working of an electromagnet is based on the magnetic effect of electric current. An electromagnet behaves as a magnet when current passes through it. Hence, it will attract a piece of iron.

(d) True

An electric bell has a piece of iron wound by a coil. When current passes through this coil, it behaves as an electromagnet.
