Question

Three different circuits (I, II and III) are constructed using identical batteries and resistors of R and 2R ohm. What can be said about current I in arm AB of each circuit
A. II > III > IIII
B. II < III < IIII
C. III < II < IIII
D. II = III = IIII

Answer 1

Answer:

option (A)

Explanation:

because current is inversely proportional to the resistance

Answer 2

Answer:

Option D is correct

Explanation:

In all the three circuits, current in the arm AB is given by E/2R(By Ohm's Law)
