Question

If a person has five resistors each of value $\frac{1}{5} \Omega$, then the maximum resistance he can obtain by connecting them is\

Professor PC Thomas Classes · Answer

(a) : The maximum resistance can be obtained from a group of resistors by connecting them in series. Thus,\ $R_{s}=\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=1 \Omega$ \Concept Applied - Combination of resistances in series have maximum value and combination of resistances in parallel have minimum value.
