Connection Made Both BulbsGlow
1) Two bulbs and two batteries connect In seriesconnection
2) Two batteries connect in parallel and twobulbs connect in series connection.
3) Two batteries connect in series and two bulbsconnect in parallel connection
4) Two batteries connect in parallel and twobulbs connect in parallel connection.

To made both bulbs brighter1. Their connection among batteries and bulbs2. Source of voltage are higher3. Low of resistance exist in circuit.
4. Higher value of total current.
* Bulbs connect in parallel and batteries connect in seriesconnection is most brighter glow of both bulbs due of high value of
total voltage and total current among others
