Q. $V - i$ graphs for parallel and series combination of two identical resistors are as shown in figure. Which graph represents parallel combination
A) $A$
B) $B$
C) $A$ and $B$ both
D) Neither $A$ nor $B$
Explanation
(a) $R_{Parallel} < R_{Series}.$ From graph it is clear that slope of the line $A$ is lower than the slope of the line $B.$ Also slope = resistance, so line $A$ represents the graph for parallel combination
