When a current passes through the body, it is mainly carried by positively charged sodium ions (Na+)(Na+) with charge +e+e and negatively charged chloride ions (Cl−)(Cl−) with charge −e−e. In a given electric field, these two kinds of ions do not move at the same speed; the chloride ions move 50%% faster than the sodium ions. If a current of 180 μAμA is passed through the leg of a patient, how many chloride ions pass a cross section of the leg per second?

rate of flow of charge is known as the flow of current.
i.e i= dQ/dt
i=180A= 180*10-6A
where Q=ne
no of charge particle
e= charge on one electron=1.6*10-19C
putting the value we get
180*10-6=n1.6*10-19/t
n/t=rate of flow of charge= 180*10-6/1.6*10-19= 1.125*1015 charge paricle per sec.
