MCQ
Two identical cycle wheels (geometrically) have different number of spokes connected from center to rim. One is having 20 spokes and the other having only 10 (the rim and the spokes are resistanceless). One resistance of value R is connected between center and rim. The current in R will be.
  • A
    double in the first wheel than in the second wheel
  • B
    four times in the first wheel than in the second wheel
  • C
    will be double in the second wheel than that of the first wheel
  • D
    will be equal in both these wheels
✓

Answer
