In this problem, we have been given that there is a 3 -on resistor and 7 -oom resistor, which is connected in parallel to each other.
00:09
And the power that is consumed by this 3 -on resistor, let's indicate that using p3, this is given as 142 watts.
00:20
And we are required to determine the power which is consumed by the 7 -on resistor.
00:26
That's p -7.
00:27
Let's take this as p -7, and we are required to find.
00:30
Find p7.
00:31
So here we use this expression to relate power with the potential difference and resistance and according to this expression, p is equal to v square by r.
00:42
So as we are given, the power dissipated across three -oom resistor.
00:46
So in that case, let's find out the potential difference across this three -oom resistor.
00:51
So that will be root of p times r...
