Neither. Connecting lamps in parallel subjects each lamp to its rated voltage, so they will each operate at their rated power (therefore brightness).
yes
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.
In parallel.
Do nothing. But in a parallel circuit, all the bulbs will get dimmer.
In a series circuit, adding more bulbs increases the total resistance, which causes the overall current to decrease. As a result, each bulb receives less voltage and therefore becomes dimmer. Thus, the bulbs will be dimmer when more bulbs are added in a series circuit.
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.
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.
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.
No. In a parallel circuit, the resistance gets cut in half, so logically the bulbs would do the opposite and get brighter.
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.
Halogen bulbs flicker on a dimmer because dimmer switches are designed for use with incandescent bulbs, not halogen bulbs. The electrical properties of halogen bulbs, such as their lower resistance when dimmed, can cause flickering when used with dimmer switches not specifically designed for them. Upgrading to a dimmer switch that is compatible with halogen bulbs can help eliminate the flickering.
