Waec Model Questions Vol1 2019 Physics Question 28
Practice objective / multiple choice question 28 from the 2019 Waec Model Questions Vol1 Physics examination.
A 12 V battery of emf E = 12 V has an internal resistance r. It is connected to two external resistors R₁ and R₂ that are in parallel. The total current drawn from the battery is 3 A and the power dissipated in R₁ is twice the power dissipated in R₂. Moreover, the power dissipated in the internal resistance equals the power dissipated in R₂. Determine the values of r, R₁ and R₂ (in ohms).
