Equivalent resistance for resistors in parallel:
Equivalent resistance for resistors in series:
Resistors C and Fare in series:
Rcf = Rc + Rf = 5.0 + 5.0 = 10Ω
Resistors CF and E are in parallel:
Rcfe = (1/Rcf + 1/Re)-1 = (1/10 + 1/10)-1 = 5.0Ω
Resistors CFE and B are in series:
Rcfeb = Rcfe + Rb = 5.0 + 5.0 = 10Ω
In the circuit at right, what is the potential at each of the noted points?
