So let us start with the concept which we are going to use here for this question.
00:07
So when two resistance connected in series, their equivalent will be given by r equivalent is equals to r1 plus r2 while if they are in parallel, so their equivalent will become r1 into r2 by r1 plus r2.
00:23
So we have been given that r1 is equals to 1000 ohm plus minus 40 ohm which is uncertainty and this is nothing but what the nominal value and this is what the uncertainty value.
00:40
Similarly r2 500 ohm uncertainty plus minus 25 ohm, voltmeter reading 10 volt, uncertainty plus minus 0 .2 volt.
00:54
So let me write down that r1 can be written as 1000 plus minus of 40 ohm with uncertainty, so that will be equals to 1000 plus minus of 4 percent.
01:09
Similarly r2 can be written as 500 plus minus 5 percent and v can be written as 10 plus minus 0 .2, this is equals to 10 plus minus 2 percent.
01:23
Okay how many percent? 2 percent was the first when they were connected in series, means the resistance will be in series combination.
01:36
So the circuit can be formed like this, means two resistance were connected in series across that battery is applied and here basically the voltmeter is connected and the current flowing throughout is in this direction, this is the r1, this is the r2...
