Electrolysis Practice Exam

Galvanism involves a continuous flow of current from one terminal to another. What type of current is this?

1. Unipolar current

2. Bi-polar current

3. Alternating current

4. Pulsed current

The correct answer is: Bi-polar current

Galvanism refers to the process of generating electricity through chemical reactions, typically using electrodes in an electrolyte solution. This term is most commonly associated with direct current (DC), which consists of the continuous flow of electric charge in one direction from anode to cathode. The type of current characterized by a continuous flow from one terminal to another is considered bipolar current, as it involves two distinct terminals: the positive (anode) and negative (cathode) poles. The nature of this current means that it consistently moves in a single direction, distinguishing it from other types of current such as alternating current, which reverses direction periodically, or pulsed current, which consists of discrete bursts or 'pulses' of current rather than a smooth, continuous flow. In the context of electrolysis, using bipolar currents can enhance efficiency in certain applications, especially in treatments like electrolysis for hair removal or skin rejuvenation. Understanding the fundamental difference between these currents is crucial in the field of electrotherapy and aesthetic treatments, as the choice of current type can affect the outcome of the procedure.
