The terminal voltage of a battery is 4.0V when supplying a current of 2.0A, and 2.0V when supplying a current of 3.0A. The internal resistance of the battery is
- 0.5 \(\Omega\)
- 1.0\(\Omega\)
-
2.0\(\Omega\)
- 4.0\(\Omega\)
The correct answer is: C
Explanation
E = 4 + 2r and E = 2 + 3rtherefore, r = 2\(\Omega\)
