Question 245: Current Electricity

Question

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 :

Accepted Answer

Resistance of each part $=\frac{R}{5}$
Total resistance $=\frac{1}{5} 	imes \frac{\mathrm{R}}{5}=\frac{\mathrm{R}}{25}$

Answer

$\frac{1}{25} \mathrm{R}$

Answer

$\frac{1}{5} R$

Answer

25 R

Answer

5 R
