Waec Model Questions Vol1 2019 Physics Question 17
Practice objective / multiple choice question 17 from the 2019 Waec Model Questions Vol1 Physics examination.
A battery of emf E volts and internal resistance r ohms is connected to a 6 Ω external resistor. The terminal voltage measured across the external resistor is 12 V. When a second identical 6 Ω resistor is connected in parallel with the first, the terminal voltage rises to 15 V. Determine the emf of the battery (in volts, to one decimal place) and its internal resistance (in ohms, to two decimal places).
