why there is no effect on the brightness of the bulb by increasing the number of cells in parallel circuit
Answers
Answer:
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.
Explanation:
What happens to the current in a parallel circuit as more light bulbs are added?
As more bulbs were added, the current increased. ... As more resistors are added in parallel, the total current strength increases. The overall resistance of the circuit must therefore have decreased. The current in each light bulb was the same because all the bulbs glowed with the same brightness.
