Determine I1, I2, and . Ch23P Page 19 CP 52 Two 75 W light bulbs are wired in series, then the combination is connected to a 120 V power supply. How much power is dissipated by each bulb? (Additional question: Repeat if the two bulbs are connected in parallel.) Ch23P Page 20 CP 57 When two resistors are connected in parallel across a battery of unknown voltage, one resistor carries a current of 3.2 A and the second carries a current of 1.8 A. How much current will be supplied by the same battery if these two resistors are connected to it in series? Ch23P Page 21 CP 58 The 10 Ω resistor in the figure dissipates 40 W of power. How much power do the other two resistors dissipate? Ch23P Page 22 Ch23P Page 23
