Lesson-42: Study of DC-AC Measuring Instruments

∴Induced current across N turns of coil = 2. BlN r d G d amps R dt R dt θ θ = (R = resistance of coil) By Lenz’s Law, torque produced = Gd G d d2 Gi G D R dt R dt dt θ θθ ===(Nm)= opposing torque. Note, G2 D R = is the damping constant for the induced currents in the coil due to its motion. ................
