Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The standard V-I characteristic curve of a solar cell is drawn in the first quadrant of the coordinate axes. Reason (R): A solar cell does not draw current from an external source but supplies current to a connected load. In the light of the above statements, choose the most appropriate answer from
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
D. (A) is not correct but (R) is correct
Step-by-step solution
A solar cell operates by supplying current to a connected load, rather than drawing current from an external source. Because it acts as a power source, the current I is taken as negative while the voltage V is positive. Therefore, its standard V-I characteristic curve is drawn in the fourth quadrant, not the first quadrant. Thus, Assertion (A) is incorrect and Reason (R) is correct. Answer: (A) is not correct but (R) is correct
