Electro Magnetic Induction And Alternating Currents Question 463
Question: 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 resistance less). One resistance of value R is connected between center and rim. The current in R will be
Options:
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
Show Answer
Answer:
Correct Answer: D
Solution:
- Since all the wires are connected between rim and axle, they will generate induced emf in parallel, hence it is same for any number of spokes.
