Question

Take input the following values from the user

R1, R2, R3, R4 R5, R6. E1 and E2.

Then print the value of the voltage across the R2 resistor.​

Answer 1

The equivalent resistance of the series connection is:

R  eq  =R+R+R+R=4Rohm

Total current in the circuit ,

I=V/R=12/4R=3/R

Reading of voltmeter A = Voltage across R 1 =I×R 1 =3/R×R=3V

Reading of voltmeter B = Voltage across R  2 =I×R 2  =3/R×R=3V

Reading of voltmeter C = Voltage across the series combination of R  3

 and

R  4 =I×(R 3 +R  4  )=3/R×2R=6V
