"RESISTANCES, SERIES and PARALLEL EQUIVALENTS.                  **** Answer to problem***                                                       First, set all resistances to 0.  type ? then (esc) 0 (enter).                  Find the equivalent of 150, 150, 150 in parallel.  Set R1=150, R2=150, R3=150.  The result is RP=50. Next, set R's to 0 by typing !? then (enter).  Move cursor to R1 and type  =RP (enter).  Move cursor to R2 and type 50 (enter).  The resultis RS=100.  Set the R's to 0. Type !? (enter).  Move cursor to R1 and type      =RS (enter).  Move to R2 and type 100 (enter).  The result of this network      analysis is an equivalent resistance RP=50 ohms.                                                                                                                                                                                                                                                                                                                                                                               ||Find the equivalent resistance of the circuit shown below.     þ          |---/\/\/\---|                                                                  |    150     |                                                             |----|---/\/\/\---|---/\/\/\---|                                                |    |    150     |     50     |                                             o--|    |---/\/\/\---|            |--o                                             |         150                  |                                                |              100             |                                                |-------------/\/\/\-----------|                                          þ    Type comma key to see answers.
