Gce Model Questions Vol1 2024 Physics Question 41
Practice objective / multiple choice question 41 from the 2024 Gce Model Questions Vol1 Physics examination.
A battery has an unknown emf \(E\) and internal resistance \(r\). When it is connected to a network consisting of a \(4\ \Omega\) resistor in parallel with a \(6\ \Omega\) resistor, the terminal voltage across the network is \(12\ \text{V}\). When the terminals are short‑circuited, the short‑circuit current is \(6\ \text{A}\). Determine the emf \(E\) of the battery and its internal resistance \(r\).
