- A 90 M2 resistor has a current of 0.68 A and is connected in series with a 110 resistor. Part A What is the emf of the battery to which the resistors are connected? Express your answer using two significant figures. IVE ΑΣΦ ε = ? kVPart A 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 170 μA is passed through the leg of a patient, how many chloride ions pass a cross section of the leg per second? Express your answer as a number of chloride ions.
