Question
Two resistors, one having a resistance of $900 \textrm{ k}\Omega$ , are connected in series to produce a total resistance of $0.500 \textrm{ M}\Omega$ . (a) What is the value of the second resistance? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
1. $-400 \textrm{ k}\Omega$
2. Resistance can't be negative
3. Either $R_1$ is too large, or $R_s$ is too small. $R_s$ is always more than any of the component resistors in series.
