Electricity & Physics Principles in Electrology Flashcards

During galvanic electrolysis, sodium hydroxide (lye) is produced at which electrode?

Answer: Cathode (negative pole)

Sodium hydroxide (NaOH) forms at the cathode (negative pole/probe) through electrolytic decomposition of tissue fluids, and this lye destroys the follicle.

Electrical resistance in body tissue is measured in which unit?

Answer: Ohms (Ω)

Resistance to electrical current flow is measured in ohms (Ω), as established by Ohm's Law relating voltage, current, and resistance.

In galvanic electrolysis, what polarity does the insertion probe carry?

Answer: Negative (cathode)

The probe is the cathode (negative pole) in galvanic electrolysis, which drives the electrochemical reaction that produces sodium hydroxide at the follicle.

When the electrologist increases the treatment intensity on a galvanic unit, what electrical parameter is being increased?

Answer: Milliamperage (mA)

Increasing intensity on a galvanic unit increases the milliamperage (mA), which determines how much lye is produced and the speed of follicle destruction.

Which type of current alternates direction of flow many times per second?

Answer: Alternating current (AC)

Alternating current (AC) periodically reverses its direction of flow at a set frequency, which is the basis for thermolysis in electrolysis.

The indifferent (dispersive) electrode used in galvanic electrolysis serves which primary function?

Answer: Complete the electrical circuit through the client's body

The indifferent electrode completes the electrical circuit, providing a return path for current that has passed through the client's tissue from the probe.

One milliampere (mA) is equal to how many amperes?

Answer: 0.001 amperes

One milliampere equals 0.001 amperes (one-thousandth of an ampere); electrology uses these very small currents for precise tissue destruction.
