V – I graphs for parallel and series combination of two metallic resistors are shown in figure. Which graph represents parallel combination?
A
A
B
B
C
Both A & B
D
Neither A nor B
Answer
A
Explanation
Solution
Slope of V-I graph gives the resistance and since graph a has smaller slope, hence it will represent smaller resistance. parallel combination of two resistor will always have smaller resistance compared to series combination.
