The brain The speech center lies in the parietal lobe of the left hemisphere of the brain for right-handed persons and most left-handed. The area of the brain responsible for motor control of the anatomic structures is called Broca ’ s motor speech area.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or a gas). In electrochemical cells, electrodes are essential parts that can consist of a variety of materials (chemicals) depending on the type of cell. An electrode may be called either a cathode or anode according to the direction of the electric ...
An electrode is a conductor through which electric current is passed. Consisting of wires, plates, or rods, electrodes are crucial...
What is Electrode? Electrodes can be defined as conductors that are used to make electrical contact with a non-metallic part of the circuit. The term was first coined by William Whewell and derived from Greek words Elektron, which means “amber” and hodos which translates to “a way.” An earlier version of an electrode was the electrophore which was used to study static electricity. It ...
Standard Hydrogen Electrode A Standard Hydrogen Electrode (SHE) is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations. It is important to have this common reference electrode just as it is ...
