Let a variable load resistance of R be connected in series with a source of EMF E volt and internal resistance r 2 (see figure). VAB represents the potential drop between A and B. Then
1
Power consumed by the load will be maximum when R = r
2
Power consumed by the load will be maximum when R = r (B) When R→ ∞, then VAB→ E
3
I vs.R graph is a straight line.
