Neco Model Questions Vol1 2023 Physics Question 4
Practice objective / multiple choice question 4 from the 2023 Neco Model Questions Vol1 Physics examination.
A battery of emf \(E\) V and internal resistance \(r\) Ω is first connected to a single resistor \(R_{1}=4\) Ω. The current measured is \(2\) A. When a second resistor \(R_{2}=6\) Ω is connected in parallel with \(R_{1}\), the current supplied by the battery becomes \(3\) A. Determine the emf \(E\) (in volts) and the internal resistance \(r\) (in ohms) of the battery.
