A wire of resistance $\mathrm{R}$ and length $\mathrm{L}$ is cut into 5 equal parts. If these parts are joined parallely, then resultant resistance will be :
Solution
<p>Resistance of each part $=\frac{R}{5}$</p>
<p>Total resistance $=\frac{1}{5} \times \frac{\mathrm{R}}{5}=\frac{\mathrm{R}}{25}$</p>
