Physics - Current Electricity Question with Solution | TestHub
Given below are two statements :
Statement I : A uniform wire of resistance is cut into four equal parts. These parts are now connected in parallel. The equivalent resistance of the combination will be .
Statement II : Two resistance and are connected in parallel in an electric circuit. The value of thermal energy developed in and will be in the ratio .
In the light of the above statements, choose the most appropriate answer from the options given below
Options:
Answer:
Solution:
Statement
When it is cut into equal parts, the resistance of each part will be,
When these resistances are connected in parallel,
Hence, the statement I is correct.
Statement 2 -
When the resistances are connected in parallel, the potential difference between them is same. Therefore, the power consumed can be written as,
Hence, statement II is incorrect.
