MCQ
For previous objective, which of the following graphs is correct
- A
- B
- C
- ✓
✓
Answer
Correct option: D.
d
(d)If at any instant, current through the circuit is i then applying Kirchoffs voltage law,$iR + e = E \Rightarrow e = E - iR.$ Therefore, graph between $e$ and $i$ will be a straight line having negative slope and having a positive intercept.
