Question

Three bulbs are having power P are connected in series in a circuit.in another circuit three bulbs of same power are connected in parallel to the same source

A)will the bulb in both the circuit glow with the same brightness? explain your answer

B.now one bulb in each circuit get fused will rest the bulb glow in each circuit ?give reason

C. Representing each bulb with a resistor draw circuit diagram for each case.

Answer 1

Yo, did you know that in most homes, the connections are in parallel?
Well this is because when you connect some thing in parallel, lets say 3 bulbs with the same power P, what you are doing is giving the circuit three different routes for the charge to go and be divided equally, thus making each of the bulbs glow with the same intensity.
But in series connection, you have just one route for the charges, so the charges won't divide, and thus all the bulbs will get the unfiltered, and powerful charges of the circuit, thus making them glow brighter than the ones in parallel.
But there's a problem. If you break the one and only route of the series connection, the whole circuit breaks, because there's only one path for the charges to flow,
but in case of parallel connection, well you have different routes, so fusing of any one of them will still make the circuit flow, and thus the 3 bulbs.
I hope you understand the concept and be able to form the diagram in your own. Peace

Answer 2

Answer:

(a)

Ans. Voltage gets divided in series combination. So bulbs in series combination will glow with less brightness. Voltage does not get divided in parallel combination, so bulbs in parallel combination will glow with more brightness.

(b)

Ans. In case of series combination, fault in even a single component will break the circuit.

So, when one of the bulbs gets fused: another bulb would continue to glow.
