Neco Model Questions Vol1 2025 Physics Question 48
Practice objective / multiple choice question 48 from the 2025 Neco Model Questions Vol1 Physics examination.
A battery of emf \(\varepsilon\) and internal resistance \(r\) is connected to a circuit as follows: a \(6\ \Omega\) resistor is in series with a parallel combination of a \(12\ \Omega\) resistor and a \(4\ \Omega\) resistor. The total current supplied by the battery is \(5.66\ \text{A}\) (to two decimal places). The power dissipated in the \(12\ \Omega\) resistor is measured to be \(24\ \text{W}\). The total power supplied by the battery is \(300\ \text{W}\). Determine the emf \(\varepsilon\) of the battery (in volts) and its internal resistance \(r\) (in ohms).
