Igcse Model Questions Vol1 2023 Physics Question 29
Practice objective / multiple choice question 29 from the 2023 Igcse Model Questions Vol1 Physics examination.
A rectangular coil of \(30\) turns has dimensions \(0.10\ \text{m}\) by \(0.20\ \text{m}\) and rotates at a constant speed of \(60\) revolutions per second in a uniform magnetic field of \(0.50\ \text{T}\). The axis of rotation is perpendicular to the field and passes through the centre of the coil. The coil is connected to a resistor of \(5.0\ \Omega\). Determine (a) the maximum current in the circuit and (b) the average power dissipated in the resistor. Give your answers to two significant figures.
