Given below are two statements:
Statement I : A uniform wire of resistance $\displaystyle 80 \Omega$ is cut into four equal parts. These parts are now connected in parallel. The equivalent resistance of the combination will be $\displaystyle 5 \Omega$.Statement II: Two resistances 2R and 3R are connected in parallel in a electric circuit. The value of thermal energy developed in $\displaystyle 3$ R and $\displaystyle 2$ R will be in the ratio $\displaystyle 3$:2.In the light of the above statements, choose the most appropriate answer from the option given below
Official answer
(3)
Statement I is correct but statement II is incorrect
