Neco Model Questions Vol1 2018 Physics Question 11
Practice objective / multiple choice question 11 from the 2018 Neco Model Questions Vol1 Physics examination.
A rectangular coil of \(N = 200\) turns and area \(A = 0.020\,\text{m}^2\) rotates at a constant angular speed of \(\omega = 120\pi\,\text{rad\,s}^{-1}\) in a uniform magnetic field of magnitude \(B = 0.50\,\text{T}\). The coil is connected in series with an external resistor of resistance \(R = 10\,\Omega\) and the coil's internal resistance \(r = 2\,\Omega\). Determine the average power dissipated in the external resistor.
