Neco 2025 Physics Question 22
Practice objective / multiple choice question 22 from the 2025 Neco Physics examination.
In a circuit a 12 V ideal battery with internal resistance \(r\) supplies two resistors \(R_{1}=6\ \Omega\) and an unknown resistor \(R_{2}\) connected in parallel. The total current drawn from the battery is \(3\ \text{A}\) and the power dissipated in \(R_{2}\) is \(12\ \text{W}\). Determine the internal resistance \(r\) of the battery and the value of \(R_{2}\) (in ohms).
