A battery of emf 12 V and internal resistance \(3 \Omega\) is connected to a resistor. If the current in the circuit is 0.8 A, the terminal voltage of the battery, will be
- A \(12 V\)
- B \(15 V\)
- C \(9.6 V\)
- D \(2.4 V\)
Answer & Solution
Correct Answer
(C) \(9.6 V\)
Step-by-step Solution
Detailed explanation
\(V = E - Ir\) \(V = 12 \,V - (0.8 \,A)(3 \,\Omega)\) \(V = 12 \,V - 2.4 \,V\) \(V = 9.6 \,V\)
