Uses for e-stim Reduction of pain and inflammation, stimulate bone/tendon growth and wound healing, muscle re-education and strengthening, replace or augment muscle function during functional activities, and evaluate nerve and muscle injury/pathology Current Represented with "I". The rate of flow of electrons through a conduction medium in response to an applied electric field. Unit is the ampere. Size of the current determines whether or not you feel a shock (AKA determines the effects...

A cylindrical wire has a resistance R and resistivity rho If its length and diameter are BOTH cut in half, what will be its resistance? 4R 2R R R/4 R/2 If its length and diameter are BOTH cut in half, what will be its resistivity? 2rho rho rho/4 rho/2 4rho Solution a)R=4L/d2 this is the original resistance now length and diameter are half means l=l/2 ,d=d/2 Rnew =4(L/2)/((d/2)2) Rnew/R =4(L/2)/((d/2)2)/4L/d2 Rnew/R =(1/2)/(1/4)/0.25 =2 Rnew =2R so the answer is B b...
