9. A battery is formed of five equal cells joined in series. When the external resistance is 4 ohms, the current is 1.5 A and when the external resistance is 9 ohms the current falls to 0.75 A, find the internal resistance (rint)of each cell. (figure 3). 10. Two lamps A and B are connected in series. Lamp A is rated 50W at 100v while lamp B is rated at 100W at 100v also. The two lamp are to be connected in series across a 200-v source. What resistance (R) must be connected across lamp A so that each lamp will operate properly? (figure 4).
