Special Edition - KCC's Quiz - World Engineering Day Quiz Equivalent Resistance

2R, since cell n represents a resistance R + (2R || 2R) = R + R = 2R and every cell sees the same 2R

2R, since cell n represents a resistance R + (2R || 2R) = R + R = 2R and every cell sees the same 2R

Right Dalitz ! The cell R-2R can be infinite and still the equivalent circuit is the resistance at the terminal side of the circuit. One can say the R-2R is transparent since one see the terminal resistance 2R. There are other structures having that transparency characteristic (see a technical article at ADI)
