How to solve this question
You have two resistors whose values you do not know, connect them in series and add 12 V.When you apply the total current through the circuit, 0.80 A and (again by applying 12 V), the same two resistorsthe total current through the circuit when you connect it in parallel; It measures 3.6 A. Their resistors are parallelCalculate the rate of energy dissipation in the smaller resistor when connected. 9 - A) 94 WB) 45 WC) 36 WD) 28 WE) 14 W
