Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
In a parallel circuit, each bulb receives the full voltage of the power source, so all bulbs shine at their full brightness. In a series circuit, the brightness of each bulb decreases as more bulbs are added because the voltage is shared among all bulbs.
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
If they have the same resistance they will. Kirchhoff's' Law.
As a series circuit, as asked, all bulbs will go off because of that just one bulb.
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
They dim as the total resistance of series of resistances is the sum of the resistances; and current = V/R.
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.
The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
To get full brightness, the rated voltage has to be applied across the bulb. When several bulbs are connected in series, the voltage gets devided among these sevral bulbs and correct rated voltage will not be applied acros each bulb, hence the brightness reduces.
The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs.
