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