Assume that you have two unknown resistors. You connect the two resistors to a power supply in series with each other and them measure the power dissipated by each. You find that the first resistor dissipates 10 W while the second resistor dissipates 15 W. Which resistor has a larger resistance? Explain.

Answer #1

second resistor (15 W ) have large resistance

p = i ^2 /R

where two resistors to a power supply in series so current same in both resistors. current is constant

power proposnal to Resistance

power increases also resistance increases

    The electronics supply company where you work has two different resistors, R1 and R2, in its inventory, and you must measure the values of their resistances. Unfortunately, stock is low, and all you have are R1 and R2 in parallel and in series - and you can't separate these two resistor combinations. You separately connect each resistor network to a battery with emf 36.0 V and negligible internal resistance and measure the power P supplied by the battery in both...
