A cell of emf 6 V and internal resistance 1 ohm is connected to an external resistor of 2 ohm. What current flows?
Answer and explanation
Correct answer: C. 2 A
- Step 1: The current is A. Answer: 2 A. Why not the others: 3 A: ignores the internal resistance. 6 A: uses the internal resistance only. 18 A: multiplies instead of dividing.
