The V-I graph for a series combination and for a parallel combination of two resistors is as shown in the figure below:
Which one of these represent parallel connection.
The correct option is A. A
A is parallel
Reason: Slope of VI graph represents resistance. The effective resistance in parallel is always lesser than that in series. As slope of A is less than that of B , A represents parallel combination.
As we know
V=IR
Req=VI=slopeofthecurve
slopeofB>slopeofA
ReqofB>ReqofA
