HowTo In the diagram shown all the wires have resistance What is current electricity class 12 physics? What is the electric current in physics 12? What is law of electric current class 12? R RESISTANCE Secrets You Won't Learn in School What is the equivalent resistance of a wire of resistance R is bent in the form of a circle? How does the resistance of a wire vary with this area of cross section?

In the diagram shown, all the wires have resistance R. The equivalent resistance between the upper and lower dots shown in the diagram is

The equivalent resistance between upper and lower dots is 3R/8. Let each wire has resistance = R

On connecting a cell between both the upper and lower end of circuit, all the wires will be connected with both the terminals.
Thus, all the 8 wires will be parallel.
Resistance of each segment = R + R + R = 3R1/ Res = 1/ 3R × 8 = 8/ 3R or = 3R/8

Therefore, the equivalent resistance between upper and lower dots is 3R/8.
