A lamp connected to a battery lights up. If a second, identical lamp is connected to the battery in parallel, the current drawn from the battery will _____ , and compared to the original brightness of the first lamp, both lamps will be _____ .
will the current increase and both lamps be brighter?
increase, identical in brightness to the original lamp.
When two identical lamps are connected in parallel to a battery, the current drawn from the battery will increase, and both lamps will have the same brightness as the original lamp.
Here's the explanation:
1. Current increase: When lamps are connected in parallel, each lamp forms a separate branch for the current to flow. In this case, the total current drawn from the battery is the sum of currents through each lamp. Since the lamps are identical, each lamp will draw the same amount of current as the original lamp, resulting in an overall increase in current.
2. Brightness remains the same: The brightness of a lamp is directly proportional to the current passing through it. Since the current through each lamp in parallel remains the same as the original lamp, both lamps will have the same brightness. Connecting lamps in parallel doesn't change the overall voltage or resistance, so the brightness remains unchanged.
Therefore, the current will increase, and both lamps will have the same brightness as the original lamp.
