Three identical resistors are connected in series. when a certain potential difference is applied across the combination, the total power dissipated is 277 w. what power would be dissipated if the three resistors were connected in parallel across the same potential difference?

2493W

Explanation:

The relationship between the power P consumed by a resistor R and the potential difference V across the it is given by;

According to the problem stated, the potential difference V is constant.

If V is kept constant, then we can write the following;

Equation (2) implies that we can write the following as long as V is kept constant;

We can simply write equation (3) as;

From the problem stated, is a series combination of three identical resistors while is their parallel combination. Let the value of each resistor be R, hence;

     (series combination)

     (parallel combination)

Given;

for the series combination, are supposed to find for the parallel combination. Hence we make the necessary substitutions into equation (4) as follows;

R cancels out from both sides and we get the following,

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

it was given as a lesson and guide for prayer.
