Description
где 4 - амплитуда переменного тока, - частота переменного тока, равна собственной частоте струны, Н - сила магнитного пол , р - плотность струны, /-площадь поперечного сечени струны, р - коэффициент затухани струны. На пр жение на концах струны, помещенной в магнитное поле и колеблющейс под вли нием проход щего через нее переменного тока, будет складыватьс из падени напр жени на омическом сопротивлении струны и обратной электродвижущей силы индукции, возгде /-длина струны.where 4 is the amplitude of the alternating current, is the frequency of the alternating current, is equal to the natural frequency of the string, H is the strength of the magnetic field, p is the density of the string, / is the area of the cross section of the string, p is the damping factor of the string. A strand at the ends of a string, placed in a magnetic field and oscillating under the influence of an alternating current passing through it, will consist of the voltage drop across the ohmic resistance of the string and the reverse electromotive force of induction, which is the length of the string.
Подставл в выражение дл выраженир дл у и дел его на / , получим эффективное сопротивление струны при резонансеSubstituting in the expression for the expression for y and doing it by /, we obtain the effective resistance of the string at the resonance
