City Guilds Model Questions Vol1 2021 Engineering Question 19
Practice objective / multiple choice question 19 from the 2021 City Guilds Model Questions Vol1 Engineering examination.
A \(120\) V supply feeds a circuit where resistor \(R_{1}\) is in series with the parallel combination of \(R_{2}\) and \(R_{3}\). The total current drawn from the supply is \(2\) A. It is known that \(R_{2}=2R_{3}\) and that resistor \(R_{3}\) dissipates \(30\) W. Find the resistance values of \(R_{1}, R_{2}, R_{3}\) in ohms, giving each answer to two decimal places.
