Answer to Question #104820 in Electric Circuits for Sisi

Question

You have 3 batteries of 1.5 V,4.5 V, and 9V of potential differences. These values are wiped off. You are supplied as well with three electric bulbs carrying rated voltages of 2V, 4.5V, and 9V. Write a plan of two main steps to get the correct voltage of the batteries, without burning out the lamps.

Answer 1

As per the given question,

Bulb can wear maximum voltage =2V, 4.5V and 9V

If we will connect these bulb in series, then the equivalent resistance of the bulb will increase and the given battries we will connect in parallel.

Hence the combination of the bulb will be in series and the combination of the batteries will be in parallel.
