A bulb A is taken and it is connected to its related potential difference. Observe its brightness. Now four identical bulb which have the same rating as A. These are connected in series and then connect the combination to rated potential difference. Now observe the brightness of A. What do you observe? Explain your observation.

Explanation:
Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.
