A) equal to the resistance of the load
B) very large as compared to the load resistance
C) zero
D) non-zero but less than the resistance of the load
Correct Answer: C
Solution :
[c] The current through the circuit is given by |
\[l=\frac{E}{R+r}\] |
where, external resistance |
internal resistance |
\[l=\frac{E}{R}\]constant, when |
