Resistors in Series and Parallel Example No2
RA is in series with R7 therefore the total resistance will be RA + R7 = 4 + 8 = 12\u03a9 as shown. This resistive value of 12\u03a9 is now in parallel with R6 and can be calculated as RB. RB is in series with R5 therefore the total resistance will be RB + R5 = 4 + 4 = 8\u03a9 as shown.
