Question

A piece of wine of resistance R is cut into five equal parts. These paste are then connected in paralle, If the equivalent resistance of this combination is R, then the ratio R/ R is. a. 1/25 b. 15 d. 25 with explanation ​

Answer 1

Answer:

They are the connected parallel. If the equivalent resistance of this combination is ${R}'$, then the ratio $\dfrac{R}{R'}$ is? So the ratio RR′=25 , which is the required answer
