Gce Model Questions Vol1 2025 Physics Question 37
Practice objective / multiple choice question 37 from the 2025 Gce Model Questions Vol1 Physics examination.
A 12\,V battery with internal resistance \(r\) supplies first a resistor \(R_1\) alone for 5\,min, then a parallel network of resistors \(R_2\) and \(R_3\) for 3\,min. The energy delivered to \(R_1\) is 1.2 times the energy delivered to the parallel network. In the parallel network the power dissipated in \(R_2\) is 30\% of that in \(R_3\). Find the ratio \(R_1 : (R_2\parallel R_3)\).
