Question

A no-turn Cu loop with diameter Phi = 4 cm rotates from the position shown t = t', to a position advanced by 90 degree, in a time interval of Delta t'' = 8 mu sec. Calculate the magnitude of the induced emf at t'', when the magnetic field is constant in time, with magnetic B^RightVector = 1.0 Tesla. emF = -126 mV emF = -10 V emF = - 50 v A series R-L-C circuit is driven by a 12.0 V_rms ac voltage source. The circuit is composed of the following components: a resistor R, R = 200 Ohm, an indicator with I = 10 mH, and a capacitor C = 10 mu F, Compute the following circuit Properties: 1) the resonant frequency f_0 in Hertz (Hz): 2) the maximum current (rms) at resonance. F_0 = 163 Hz, i_rms = 20 mA F_0 = 120 Hz, i_rms = 1 mA F_0 = 263 Hz, i_rms = 77 mA F_0 = 504 Hz, i_rms = 60 mA
