Given below are two statements:
Statement I : The equivalent resistance of resistors in a series combination is smaller than least resistance used in the combination.
Statement II : The resistivity of the material is independent of temperature. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Statement and Statement are false
- BBoth Statement and Statement are true
- CStatement is true but Statement is false
- DStatement is false but Statement is true
Correct answer
A. Both Statement and Statement are false
Step-by-step solution
The formula for series equivalent resistance is given by
.
Hence, the equivalent resistance will be the highest value compared to other resistances.
The resistivity of a material is given by,
Clearly, the resistivity is dependant on temperature.
Hence, this is the right option.
