A Bulb can be connected in a series in such a way that the energy source which is applied want to flow equally across the bulbs connected in series.
A Bulb has to knobes or holds in which we supply the power.
Assume one knob as a positive voltage absorbing source and other has a negative voltage absorbing source. When we connected in such a way that we can apply the voltage continuously in which the bulb will blow easily. When two or more bulbs are connected in series like end of the knob of one bulb i.e., negative to the next positive of the next bulb in series and negative of second bulb to the positive of the third bulb. Then the voltage splits equally across the bulbs connected.
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.

Your description is very strange. I can't imagine an application where two bulbs are in series and two in parallel. However let's assume that each bulb has one white wire and one black wire. Take the two parallel bulbs and connect then across the supply by tying all blacks and all whites together with black and white from supply. Then for the two series bulbs connect black from one to white from other. Then take the remaining black and white wires and connect to the black and white wires for parallel bulbs respectively.
If you connect bulbs in parallel across a given voltage supply (eg household mains supply) then they will all draw their rated current and will glow at their rated brightness. If you connect the same bulbs in series then they will glow very much less brightly. This is because the resistance of a bulb's element is also related to the power dissipated in the element. A bulb's element is rated for operation at a particular voltage. You can certainly connect two 6v motorcycle bulbs in series, and connect them to a car battery at 12v, and the two bulbs will be just as bright as they were when individually operated from the motorcycle 6v batttery. However if you connect two 6v bulbs in parallel and then wire them to a 12v car battery they will only glow brighter for a fraction of a second and then ... pop. You will have overheated the elements beyond their designed power handling capability.
When two identical 115-volt light bulbs are connected in series to a 240-volt supply, the voltage is divided equally between the two bulbs. Each bulb would receive 120 volts, which is higher than their rated voltage of 115 volts. This excess voltage can cause the bulbs to overheat and potentially burn out quickly, leading to a failure of both bulbs. Thus, it's not recommended to connect them in this manner.

The switch will not increase the current. The only thing that will increase the current is adding a larger load.Another AnswerTo maximize current flow in a circuit with 2 Flashlightbatteries, 2 Flashlight bulbs, and a switch, set aside the bulbs, put the batteries in series, connect the switch between the end poles of the battery set, and close the switch. The batteries will get hot and probably leak electrolyte, and be drained in seconds.If you want to maximize current through the circuit withthe bulbs in it, connect the bulbs in parallel to each other, and in series with the switch.
Disadvantage of series connection: 1.If one point breaks in the series circuit, the total circuit will break. 2.suppose if you want to connect 3 bulbs rated 230v,5A in series then due to added up resistance less current flows and the bubs are dimmer
To wire two bulbs to one switch, connect the live wire from the switch to the live terminal of the first bulb. Then connect a wire from the live terminal of the first bulb to the live terminal of the second bulb. Finally, connect the neutral wire from the switch to the neutral terminals of both bulbs. This setup will allow the switch to control both bulbs simultaneously.
As a series circuit, as asked, all bulbs will go off because of that just one bulb.
The voltage in a series circuit is divided among the bulbs, so as more bulbs are added in series, each bulb receives less voltage. This causes the brightness of each bulb to decrease compared to when fewer bulbs are present.
If you connect three identical bulbs in series to a 5-volt battery, the total voltage will be divided equally among the bulbs, resulting in a reading of approximately 1.67 volts across each bulb. If you measure the voltage across the entire series circuit, the voltmeter will read 5 volts. However, if the bulbs are connected in parallel, the voltmeter will still read 5 volts across each bulb, as they each receive the full voltage of the battery.
