Gce Model Questions Vol1 2019 Physics Question 14
Practice objective / multiple choice question 14 from the 2019 Gce Model Questions Vol1 Physics examination.
In a circuit a battery of emf \(E\) and internal resistance \(r\) is connected to an external resistor \(R\). When \(R = 5.0\ \Omega\) the current measured is \(2.0\ \text{A}\) and the terminal voltage across the resistor is \(8.0\ \text{V}\). When \(R\) is changed to \(10.0\ \Omega\) the current falls to \(1.5\ \text{A}\). Determine the emf \(E\) of the battery and its internal resistance \(r\).
