Q1:

In a certain five-step R/2R ladder network, the smallest resistor value is 1 k. The largest value is

A indeterminable

B 2 k

C 10 k

D 20 k

ANS:B - 2 k

It is just a continuous 5 step R, 2R, R, 2R network.

The smallest value is are (1k) and largest value is 2R (2k). If it is 10 or 20 step network. Doesn't matter, the value is still R and 2R.
