1.Two resistors A and B are connected in series across 220V DC source. When a voltmeter with a internal resistance of 10kΩ is connected across resistor A, the instrument reads 100V and when connected across resistor B, it reads 80V. Find Resistor A and B.
2. A potential divider of resistance of 50Ω is connected across a 100V Dc source. A load resistance of 10Ω is connected across a tap in the potential divider and the negative terminal of the source. If a current of 4A flows towards the load, What is the current supplied by the source?
PLEASE I REALLY NEED HELP SOLVE THESE TWO PROBLEM..
BTW WHO HAVE A PDF OF MCGRAWHILL BOOK IN ELECTRICAL CIRCUITS THANKS !!!
