(b) What can you do if you need a 35 resistor?
Transcribed Image Text:(a) You need a 45 resistor, but the stockroom has only 20 Q and 50 resistors. How can the desired resistance be achieved under these circumstances?
O Put two 50 Q2 resistors in series and then put that combination in parallel with a 20 Q resistor.
O Put two 50 resistors in parallel and then put that combination in series with a 200 resistor.
O Put one 50 and one 20 resistor in series and then put that combination in parallel with a 200 resistor.
O Put one 50 and one 2002 resistor in parallel and then put that combination in series with a 20 resistor.
(b) What can you do if you need a 35 Q resistor?
O Put two 50 resistors in parallel and two 20 Q resistors in parallel. Then put these two combinations in series.
O Put one 50 and one 20 Q resistor in series and two 20 resistors in series. Then put these two combinations in parallel.
O Put one 50 and one 2002 resistor in parallel and two 20 Q resistors in parallel. Then put these two combinations in series.
O Put two 50 Q resistors in series and two 20 resistors in series. Then put these two combinations in parallel.
