City Guilds Model Questions Vol1 2025 Engineering Question 26
Practice objective / multiple choice question 26 from the 2025 City Guilds Model Questions Vol1 Engineering examination.
An electrical circuit consists of a resistor \(R_1 = 4\ \Omega\) in series with a parallel combination of two resistors \(R_2\) and \(R_3\). The equivalent resistance of the whole circuit is \(6\ \Omega\). When a voltage of \(12\ \text{V}\) is applied across the circuit, the power dissipated in \(R_2\) is twice the power dissipated in \(R_3\). Determine the resistance \(R_2\) (in ohms).
