Question Question 28
In which of the following cases the bulb will glow:
(i) Only one terminal of a cell is joined with a metal wire to one terminal of the bulb.
(ii) Both terminals of the bulb are joined with two metal wires to one terminal of the cell.
(iii) One terminal of the cell is joined to one terminal of the bulb and other terminal of the cell to the other terminal of the bulb.
The bulb will glow in third case i.e. One terminal of the cell is joined to one terminal of the bulb and other terminal of the cell to the other terminal of the bulb.
In this case the circuit is complete allowing the flow of electricity so bulb will glow.
