Gce Model Questions Vol1 2018 Physics Question 13
Practice objective / multiple choice question 13 from the 2018 Gce Model Questions Vol1 Physics examination.
A battery of unknown emf \(E\) V and internal resistance \(r\) \(\Omega\) is connected to a variable external resistor \(R\). When \(R=6\) \(\Omega\) the terminal voltage measured across the external resistor is \(9\) V. When \(R=3\) \(\Omega\) the terminal voltage is \(8\) V. Determine the emf \(E\) of the battery (to two significant figures) and its internal resistance \(r\) (to two significant figures).
