HOW can the desired resistance be achieved under these circumstances? ,F] Put two 50 SI resistors in parallel and then put that Combination in series with a 20 El resistor. 3 Put one 50 and one 20 [I resistor in series and then put that Combination in parallel with a 20 Q resistor. '_] Put two 50 S1 resistors in series and then put that combination in parallel with a 20 1 resistor. Cl Put one 50 and one 20 [I resistor in parallel and then put that combination in series with a 20 X! resistor. (b) What can you do if you need a 35 52 resistor7 :1 Put one so and one 20 :2 resistor in parallel and two 20 :2 resistors In parallel. Then put these two combinations in series. Cl Put two 50 {I resistors in parallel and two 20 [I resistors in parallel. Then put these two combinations in series. J Put one 50 and one 20 2 resistor in series and two 20 Q resistors in series. Then put these two combinations in parallel. Cl Put two 50 (.2 resistors in series and two 20 2 resistors in series. Then put these two combinations in parallel. 4.

When the double-throw switch 5 is open as shown in the figure, the current in the battery is 1.09 mA, When the switch is closed in position a, the current in the battery is 1.22 mA. When the switch is closed in position b, the Current In the battery is 2.09 mA. Find the following resistances. (a) R1 l m (b) R2 l m (C) R3 l m
