Lamps connected in parallel are subject to the same voltage. Provided this voltage corresponds to the lamps' rated voltage, then each lamp will operate at its rated power and at its full rated brightness.
Individual lamps connected in series operate below their rated voltage (the sum of the voltage drops around a series circuit equals the supply voltage) and will, therefore, operate below their rated power and brightness. The lamps will vary in brightness; those with the lower power ratings will be brightest and those with the higher power ratings will be least bright.
In parallel.
Brighter in parallel. In series the voltage is divided between the two bulbs, thus the current will only be half so that the power of each bulb will only be one quarter (of 5 watts) in the series set-up.
In a parallel circuit, each light bulb would receive the full voltage of the power source, allowing them to burn brighter compared to a series circuit where the voltage is divided among the bulbs.
In parallel, each bulb will have full voltage applied across them. However, in series, the voltage across each bulb won't be the same as supply voltage. Thereby, bulbs connected in parallel will glow brighter.
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.
Parallel connections will draw more current than equivalent lights connected in series, so the parallel configuration will be brighter.
In a parallel circuit, the brightness of the bulbs connected depends on their resistance and current flow, not their physical shape or size. The bulbs will have the same voltage across them, so if the long bulb has a lower resistance, it could be brighter but this depends on the specific characteristics of the bulbs.
parallel
Neither. Connecting lamps in parallel subjects each lamp to its rated voltage, so they will each operate at their rated power (therefore brightness).
Parallel. Coz all the elements will get same voltages from the sources. in case of series connection, the voltage is divided between all elements.
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
