Anode is Positive or Negative
Since electrons carry a negative charge then the anode is negatively charged. In the general sense current refers to any movement of electrical charge. Pin On Med Tech Anode and cathode are two terms that are often used interchangeably with positive and negative in batteries. . The negative electrode is called the cathode while the positive electrode is called the anode. Anode is negative in electrochemical cell because it has a negative potential with respect to the solution while anode is positive in electrolytic cell because it is connected to positive terminal. Think of a large parallel capacitor. However in some experiments such as Gel Electrophoresis the anode is positive. The terms anode cathode positive and negative are not synonymous they can sometimes be confused which can lead to errors. In a galvanic voltaic cell the anode is considered negative and the cathode is considered positive. The catho...
