Calculate the potential difference across the resistor of 400 Omega as measured by the voltmeter V of 400 Omega either by applying Kirchhoff's laws or otherwise |
Answer» SOLUTION :The given circuit may be redrawn as follows: Clearly this is a case of balanced Wheat-Stone Bridge. The 100Omega and D can be removed Now the reading of the voltmete`r = V_(BC) = I_(1), (200Omega) =(10V)/((100+200)Omega)XX(200Omega)=(20)/(3)Volt`
