Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
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.
In a parallel circuit, adding more light bulbs won't affect the brightness of the original bulb because each bulb has its own separate path for the current to flow. Each bulb receives the same voltage as the power source, ensuring that each bulb will shine at its designated brightness independently of the others.
This has to do with the potential difference(voltage) reaching each bulb.If the bulbs are placed in series, the voltage will be divided among them(for example, 9V battery powering two identical bulbs will result in each bulb getting 4.5V). Thus, they would each only be One fourth as bright than if there was a single bulb as the power is Voltage squared. If Voltage is halved then power goes one fourth.If the bulbs are placed in parallel, the current(amperage) is divided instead, resulting in each bulb getting the same voltage. This will result in both bulbs having brightness equal to a single bulb.
In a parallel circuit, as more bulbs are added, the overall brightness of the bulbs remains constant. This is because each bulb gets the full voltage of the circuit and operates independently of the other bulbs. The individual brightness of each bulb may decrease slightly due to the increased current draw, but the overall brightness of the circuit remains fairly consistent.
In a parallel circuit, when one light bulb goes out, the other bulbs will continue to operate as they each have their own separate path for current flow. The brightness of the remaining bulbs will not be affected by the one that went out.

The brightness of each bulb in a parallel circuit is the same as the brightness of a bulb in a simple circuit. By Kirchoff's voltage law, each element of a parallel circuit has the same voltage drop across it. With the same voltage, the same type of bulb will dissipate the same power, and have the same brightness.
Then the brightness of the light buld increases.
The brightness of three bulb would be mare than one

If a rheostat is connected in parallel with a light bulb, the setting of the rheostat should have no effect on the performance of the light bulb, as long as the power supply is able to maintain its output voltage and deliver the current demanded by their parallel combination.
In a parallel circuit, when one light bulb goes out, the other bulbs will continue to operate as they each have their own separate path for current flow. The brightness of the remaining bulbs will not be affected by the one that went out.
The pencil lead does not have a significant effect on the brightness of the bulb in a circuit because it does not conduct electricity efficiently. In order for the bulb to light up brightly, the circuit needs an efficient conductor such as a metal wire to allow the current to flow easily and light up the bulb.
The light bulb was likely the dimmest in the circuit where it had the highest resistance, creating more opposition to the flow of current, resulting in less brightness.
