Q:

What is faradic current?

A:

According to Hawkins International, "faradic current" is produced from an interrupted direct current and is derived from either rectified mains current or batteries. It can also be defined as current corresponding to the oxidation or reduction of a chemical species.

According to Reference.com, the term "faradic" pertains to a discontinuous, alternating, asymmetric current from the secondary winding of an induction coil. The faradic or induction coil was discovered in 1831 by Faraday. The origin of the word "faradic" is from the French word "fardique," dating back to the late 19th century. Both faradic currents and sinusoidal currents have a frequency of 50 cycles per second and can cause tetranic contractions of voluntary muscles.

  • Q:

    How does a galvanic current work?

    A:

    A galvanic current is a direct current that is constant and rectified to a voltage level that is safe and low. As the current passes through salt and acid-containing solutions, chemical changes occur. Changes also occur when the current travels through body fluids and tissues.

  • Q:

    What is the purpose of a rectifier?

    A:

    Rectifiers are used in electrical circuits to covert alternating current to direct current. They employ diodes, electrical devices that permit the flow of current in one direction only, to accomplish this conversion.

  • Q:

    How are current and voltage related?

    A:

    Voltage, or electrical pressure, in a system produces a proportionate amount of current when placed across electrical resistance. Ohm's law indicates that 1 volt passed through 1 ohm of resistance produces 1 ampere of current, or electrical flow. Voltage and current, therefore, have a direct relationship most of the time.

    What is the difference between faradic and galvanic current?

    A:

    A faradic current is an alternating, asymmetric current that stimulates muscles throughout its nerve, according to the University of Buffalo. A galvanic current is a term mostly used in medicine meaning a direct current of steady flow.
