When a current passes through the body, it is mainly carried by positively charged sodium ions (Na+) with charge +e and negatively charged chloride ions (Cl-) with charge -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 150 μA is passed through the leg of a patient, how many chloride ions pass a cross section of the leg per second?

Current describes the rate of electricity (how fast charges are moving). Its formula is I=q/t. The higher the current, the more charges are flowing per unit time.
