(a) You need a 45 2 resistor, but the stockroom has only 20 2 and 50 resistors. How can the desired resistance be achieved under these circumstances? ✔Put one 50 and one 20 2 resistor in parallel and then put that combination in series with a 20 2 resistor. Put two 50 resistors in series and then put that combination in parallel with a 20 12 resistor. Put two 50 2 resistors in parallel and then put that combination in series with a 20 02 resistor. Put one 50 and one 20 2 resistor in series and then put that combination in parallel with a 20 12 resistor. x (b) What can you do if you need a 35 2 resistor? Put two 50 resistors in series and two 20 2 resistors in series. Then put these two combinations in parallel. Put one 50 and one 2002 resistor in series and two 20 resistors in series. Then put these two combinations in parallel. Put one 50 and one 20 $2 resistor in parallel and two 20 02 resistors in parallel. Then put these two combinations in series. Put two 50 2 resistors in parallel and two 20 02 resistors in parallel. Then put these two combinations in series. 4
