this is because due to the less amount of resistance there is huge amount of current which is sufficient to melt the filament which is present inside the bulb.
Explanation:
- As a result of this if the person wants to connect one at a time he should also add another resistance of high-value so that the total resistance of the circuit increases.
- As a result of this since the voltage remains constant the current flowing in the circuit will decrease and as a result of this there will be less heat generated in the filament and we won't get melted
