The electronics supply has tow different resistors: R1 and R2. In ist inventory and you must the values of their resistance. Stock is low, and all you have are R1 and R2 in parallel and series. Can´t separate the tow resistors combination. You separately connect each resistor network yo a battery emf 48V and negligible internal resistance and measure the power P supplied by the battery in both cases. For the series combination, P = 48W. for the parallel combination, P= 256W. You are told that R1>R2.
 a) Calculate R1 and R2.
b) For the series combination, wich resistor consumes more power?
c) For the parallel, wich resistor consumes more power?
Your answer is partially correct.
