Question

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

• A. Power consumed by the load will be maximum when R = r
• B. Power consumed by the load will be maximum when R = r (B) When R→ ∞, then VAB→ E
• C. I vs.R graph is a straight line.
• D. VAB increases with increasing

Answer 1

Answer: (A), (B)

Power consumed by the load will be maximum when R = r

Answer 2

The correct option is: A and B
