City Guilds Model Questions Vol1 2021 Engineering Question 41
Practice objective / multiple choice question 41 from the 2021 City Guilds Model Questions Vol1 Engineering examination.
In a DC circuit, a resistor \(R_{1}=10\ \Omega\) is connected in series with a parallel combination of resistors \(R_{2}\) and \(R_{3}\). When a \(12\ \text{V}\) source is applied across the whole circuit, the measured total current is \(0.5\ \text{A}\). It is also known that the power dissipated in \(R_{2}\) is half the power dissipated in \(R_{3}\). Determine the resistance of \(R_{2}\) (in \(\Omega\)).
