NEET Physics Resistors in Parallel Assertion Reason Question
Given below are two statements:
Statement I: A uniform wire of resistance 80 Ω is cut into four equal parts. These parts are now connected in parallel. The equivalent resistance of the combination will be 5 Ω.
Statement II: Two resistances 2R and 3R are connected in parallel in a electric circuit. The value of thermal energy developed in 3R and 2R will be in the ratio 3:2.
In the light of the above statements, choose the most appropriate answer from the option given below
Both statement I and statement II are correct
Both statement I and statement II are incorrect
Statement I is correct but statement II is incorrect
Statement I is incorrect but statement II is correct
Correct Answer
Detailed Explanation
Statement I is correct as the equivalent resistance of four 20 Ω resistors in parallel is 5 Ω. Statement II is incorrect as the thermal energy ratio should be 2:3.
