Question

The maximum resistance which can be made using four resistors each of resistance $\frac{1}{2} \Omega$ is\

Professor PC Thomas Classes · Answer

(a) : The maximum resistance can be produced from a group of resistors by connecting them in series. Thus, $R_{\mathrm{s}}=\frac{1}{2} \Omega+\frac{1}{2} \Omega+\frac{1}{2} \Omega+\frac{1}{2} \Omega=2 \Omega$\
