Question:

From Ohm's law for circuits, it follows that the total resistance Rtot of two components hooked in parallel is given by the equation

R¡R2 Riot R1 + R2


where R1 and R2 are the individual resistances.

(a) Let R1 = 10 ohms, and graph Rtot as a function of R2.

(b) Find and interpret any asymptotes of the graph obtained in part (a).

(c) If R2 = 2ˆšR1, what value of R1 will yield an Rtot of 17 ohms?
