The power P delivered to each resistor is the product of thecurrent squared (I^2) and the corresponding resistance R, or P =I^2*R. The resistances are known, and Ohm's law can be used to findthe current. Ohm's law states that the current in the circuit(which is also the current through each of the resistors) equalsthe voltage V of the battery divided by the equivalent resistanceRs of the two resistors: I = V/Rs. Since the resistors areconnected in series, we can obtain the equivalent resistance byadding the resistances.
Three resistors, 3 O, 4.5 O, and 5.5 O, are connected in seriesacross a 12-V battery. Find the power delivered to eachresistor.
