GitBook practice — Set 4 (Ashadh, 2081)

A$$\frac{1}{\mathrm{~~j~~}} = \frac{\tau\_{\mathrm{max}}}{\mathrm{~~R~~}} = \frac{\mathrm{C}\theta}{\mathrm{~~l~~}}$$

B$$\frac{1}{\mathrm{~~j~~}} = \frac{\tau\_{\mathrm{max}}}{\mathrm{~~R~~}} = \frac{\mathrm{C}\theta}{\mathrm{~~l~~}}$$

C$$\frac{1}{\mathrm{~~j~~}} = \frac{\mathrm{R}}{\mathrm{~~l~~}} = \frac{1}{\mathrm{\~C}\theta}$$

D$$\frac{1}{\mathrm{~~j~~}} = \frac{\mathrm{R}}{\mathrm{~~l~~}\_{\mathrm{max}}} = \frac{\mathrm{C}\theta}{\mathrm{~~l~~}}$$
