How to Determine Brightness of Lamps in Different Resistances
What happens when two lamps with different resistances are connected in parallel?
(A) The lamp with greater resistance becomes brighter
(B) The lamp with less resistance becomes brighter
What happens when two lamps with different resistances are connected in series?
(A) The lamp with greater resistance becomes brighter
(B) The lamp with less resistance becomes brighter
Answer:
The brightness of lamps in different resistances depends on how they are connected, either in parallel or in series.
When two lamps with different resistances are connected in parallel, the lamp with less resistance becomes brighter. This is because the total resistance decreases compared to the resistance of each individual lamp. As a result, the lamp with less resistance will draw more current and emit more brightness.
On the other hand, when the two lamps are connected in series, the lamp with greater resistance becomes brighter. In this case, the total resistance increases compared to the resistance of each individual lamp. As a result, the lamp with greater resistance will draw more current and emit more brightness.
Therefore, to determine the brightness of lamps with different resistances, consider how they are connected in a circuit.
