THE EFFECT OF SALT BRIDGE’S ELECTROLYTE VARIATION TOWARDS CU/ZN GALVANIC CELL IMPEDANCE

A battery consist of three main parts, namely anode or the negative pole, cathode or the positive pole and electrolyte. The electrolyte role in a battery is to maintain the electrical neutrality both side of the electrodes. Electrolyte consists of cation and anion that has different ionic mobility i...
