Question

Umesh has two bulbs having
resistances of 15 22 and 30 92. He wants to connect them in a circuit,but if he connects them one at a time the filament gets burnt. Answer the following
A. Which method should he use to connect the bulbs?

B. What are the characteristics of this way of connecting the bulbs depending on the answer of question A above?

C. What will be the effective resistance in above circuit?

pleace give the answers correct .
i will marked u as brainliest if the answers are correct.​

Answer 1

Answer:

Explanation:

A. To connect the bulbs, he should use parallel connection. This is because both the bulbs are of different resistances. Hence, if we connect in series, the low resistance one might get burnt. Also the net current provided will also decrease. Thus parallel connect should be used.

B. 1. It ensures that both the bulbs get the required current and voltage.

  2. If one bulb damages the other one won't damge at the same time.

  3. The net current received will be sufficient for functioning.

C. Please solve this using the formula, as I don't think the values given are correct, since such high resistances aren't possible.

HOPE THIS HELPS YOU...
