1.	A wire of resistance R1 is cut into five equal pieces. These five pieces of wire are then connected in parallel. If the resultant of this combination be R2 then the ratio R1R2 is: (a) 125 (b) 15 (c) 5 (d) 25
Answer» A wire of resistance $R_{1}$ is cut into five equal pieces. These five pieces of wire are then connected in parallel. If the resultant of this combination be $R_{2}$ then the ratio $\frac{R_{1}}{R_{2}}$ is: (a) $\frac{1}{25}$ (b) $\frac{1}{5}$ (c) 5 (d) 25
