Neco Model Questions Vol1 2017 Physics Question 17
Practice objective / multiple choice question 17 from the 2017 Neco Model Questions Vol1 Physics examination.
An ideal battery of emf \(E\) and internal resistance \(r\) supplies a resistor of resistance \(R\). When a second resistor of resistance \(2R\) is connected in parallel with the first resistor, the terminal voltage of the battery drops by 20\% compared with the terminal voltage when only the resistor \(R\) is connected. Determine the ratio \(\dfrac{r}{R}\).
