Ncert Exercises & Solutions

Let there be n resistors $R_{1} . . . . . . . . . . R_{2}$ , with $R_{\max} = \max (R_{1} . . . . . . . . . . . . . R_{n})$ and $R_{\min} = \min (R_{1} . . . . . . . . . . . . . R_{n})$ . Show that when they are connected in parallel, the resultant resistance $R_{p} < R_{\min}$ and when they are connected in series, the resultant resistance $R_{s} > R_{\max}$ . Interpret the result physically.
