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
