Igcse Model Questions Vol1 2023 Physics Question 2
Practice objective / multiple choice question 2 from the 2023 Igcse Model Questions Vol1 Physics examination.
A rectangular coil of \(N = 200\) turns rotates in a uniform magnetic field of magnitude \(B = 0.10\ \text{T}\). The coil has an area of \(A = 0.020\ \text{m}^2\) and rotates at a frequency of \(f = 50\ \text{Hz}\). The resistance of the coil itself is \(5.0\ \Omega\). The coil is connected to an external load resistor \(R_L\).\n\n(a) Determine the value of \(R_L\) that will allow the maximum average power to be delivered to the load.\n(b) Calculate that maximum average power (in watts), giving your answer to three significant figures.
