  • The main use of electrodes is to generate electrical current and pass it through non-metal objects to essentially alter them in several ways. Electrodes are also used to calculate conductivity.
  • The electrode is the location where electron transfer happens. An electrode is classified as either a cathode or an anode counting on the type of chemical response that happens. If an oxidation reaction happens at an electrode.

<h2>Answer:</h2><h2>Human blood grouping is mainly based on the antigens present on their RBC (red blood cells) and in plasma into various groups but the main antigens are namely A/B and Rh antigens.</h2><h2 /><h2>Depending on A/B antigens humans are grouped (ABO Grouping) into</h2><h2 /><h2>A group: those having A named antigen on their RBC.</h2><h2 /><h2>B group: those having B Antigen on their RBC.</h2><h2 /><h2>AB group : Those having both A B antigens on their RBC.</h2><h2 /><h2>O group: those having no antigens on their RBC.</h2><h2 /><h2>Depending on the presence of Rh antigens they are grouped into Rh positive or negative group.</h2><h2 /><h2>So if the person has both A and Rh antigens then he will be A positive blood group. But having only A antigen but not Rh Antigen then he will be A negative group.</h2>

<h2>Extra Information:</h2><h2>In addiition to these there is also the HH group. The peculiarity is that they do not express the H antigen. As a result they cannot form A antigens or B antigens on their red blood cells. Thus they can donate blood to anybody with ABO grouping but can receive blood only from Bombay blood group people.</h2><h2 />
