Question
In the circuit shown in Figure, an ideal ohmmeter is connected across ab with the switch S open. All the connecting leads have negligible resistance. What will be the ohmmeter reading in Ohms (with two decial places) if R1 = 7.9 ?; R2 = 6.1 ? and R3 = 4.4 ??

R_eq = 1/(1/(10+15+20) + 1/7.9 + 1/6.1 + 1/4.4) = 1.85 ohms
