Neco Model Questions Vol1 2019 Physics Question 16
Practice objective / multiple choice question 16 from the 2019 Neco Model Questions Vol1 Physics examination.
An ideal rectangular coil of \(N = 200\) turns and area \(A = 0.020\,\text{m}^2\) rotates uniformly in a uniform magnetic field of magnitude \(B = 0.50\,\text{T}\). The coil rotates at a frequency of \(f = 50\,\text{Hz}\) and its terminals are connected across a resistor of resistance \(R = 10\,\Omega\).\n\n(a) Determine the maximum induced emf in the coil.\n(b) Find the average electrical power dissipated in the resistor.\n(c) Assuming the mechanical power supplied to keep the coil rotating equals the electrical power dissipated, calculate the torque that must be applied to the coil shaft.
