Neco Model Questions Vol1 2018 Physics Question 27
Practice objective / multiple choice question 27 from the 2018 Neco Model Questions Vol1 Physics examination.
A battery of unknown emf \(E\) volts and internal resistance \(r\ \Omega\) is connected to a resistor of \(8\ \Omega\). The terminal voltage across the resistor is measured to be \(6\ \text{V}\). When a second resistor of \(12\ \Omega\) is added in series, the terminal voltage across the combination becomes \(7\ \text{V}\). Determine the emf \(E\) (in volts) and the internal resistance \(r\) (in \(\Omega\)).
