Metals are good conductors of electricity because they have a high number of free electrons that can easily move through the material when an electric current is applied. This allows the electricity to flow easily without much resistance. In contrast, concrete, mountain rocks, and wooden fence poles do not have a high number of free electrons and therefore do not conduct electricity as well as metals.

Alternating current is the correct answer because the question is asking for the other kind of electric current besides direct current. Alternating current is a type of electric current that periodically reverses direction, unlike direct current which flows in only one direction. Therefore, it is the appropriate choice to complete the statement.

A steamer or vaporizer produces moist uniform heat that can be applied to the head or face. Ultraviolet rays are not used for producing heat and Tesla high frequency current is not typically used for this purpose either. Cold rags do not produce heat at all. Therefore, the correct answer is steamer or vaporizer.

An insulator or non-conductor is a substance that does not easily transmit electricity. Cement is included as an example of an insulator because it does not conduct electricity well.

An electrode is a device that conducts electricity and is used to deliver electric current from a machine to the client's skin. It is commonly used in various medical and cosmetic procedures, such as electrotherapy and electrolysis. The electrode acts as a connector between the machine and the client's skin, allowing the flow of electric current to achieve the desired therapeutic or cosmetic effect.

Electricity, when in motion, exhibits magnetic, chemical, and thermal effects. This means that it can generate heat or be converted into heat energy. Thermal energy is a form of energy that is associated with the motion of particles within a substance. When an electric current flows through a conductor, it can produce heat due to resistance in the material. Therefore, the correct answer is thermal.

The apparatus that changes direct current to alternating current is called a converter. A converter is an electrical device that converts the input direct current into an output alternating current, allowing for the transfer of electrical power between different systems or devices. It is commonly used in various applications such as power electronics, renewable energy systems, and electric vehicles.

The positive electrode of electrotherapy devices is called the anode. In electrotherapy, the anode is the electrode through which the positive current flows into the body. It is responsible for attracting negatively charged ions and promoting various therapeutic effects such as pain relief and tissue healing. The anode is commonly used in galvanic electrotherapy, where direct current is applied to the body for therapeutic purposes.

Desincrustation is a process used to treat acne. It involves the use of a galvanic current to soften and liquefy sebum and other impurities in the pores, making it easier to remove them. This treatment can help to unclog pores, reduce inflammation, and improve the overall appearance of the skin.

Iontophoresis is the correct answer because it refers to the process of introducing water-soluble products into the skin using electric current. This technique is commonly used in skincare treatments to enhance the absorption of certain substances into the skin, such as medications or serums. By applying a low-level electric current, iontophoresis helps to push the products deeper into the skin, allowing for better penetration and effectiveness.

Cataphoresis is a process that uses galvanic current to force acidic substances into deeper tissues. The positive pole is used to attract the acidic substances and push them towards the negative pole. This technique is commonly used in skincare treatments to deliver beneficial ingredients deep into the skin, helping to improve its condition and appearance.

Infrared rays make up 60% of natural sunlight. Infrared rays are a type of electromagnetic radiation that has longer wavelengths than visible light. They are not visible to the human eye but can be felt as heat. Sunlight consists of various types of electromagnetic radiation, including infrared rays. The given answer suggests that 60% of the energy in natural sunlight is made up of infrared rays.

High frequency current is a type of electrical current that is commonly used in beauty treatments. It is not recommended to use high frequency current on clients who have certain medical conditions, such as asthma. This is because asthma is a respiratory condition that can be triggered or worsened by electrical stimulation. Therefore, using high frequency current on a client with asthma could potentially exacerbate their symptoms and cause discomfort or harm.

Ultraviolet rays make up a very small percentage of natural sunlight, approximately 5%. This is because sunlight consists of a broad spectrum of electromagnetic radiation, including visible light, infrared rays, and ultraviolet rays. While ultraviolet rays are responsible for causing sunburn and other skin damage, they make up only a small fraction of the overall sunlight.

Catalysts are substances that are used to increase the rate of a chemical reaction without being consumed in the process. They work by providing an alternative pathway for the reaction to occur with lower activation energy. This lowers the energy barrier for the reaction, allowing it to happen more quickly. Unlike other options such as a vibrator, heat lamps, or electromagnetic radiation, catalysts specifically facilitate chemical reactions and are not consumed or altered in the process.

The positive pole (anode) is known to decrease blood supply. When the positive pole is applied to the body, it causes vasoconstriction, which is the narrowing of blood vessels. This constriction reduces the flow of blood to the area, resulting in a decrease in blood supply.

The correct answer is "acidic substances into deeper tissues." When galvanic current is applied from the positive pole (anode) to the negative pole (cathode), it causes chemical changes to occur as it passes through the tissues. These chemical changes result in the introduction of acidic substances into deeper tissues.

Anaphoresis is the process of forcing liquids into the tissues from the negative toward the positive pole. It is a technique commonly used in electrotherapy, where an electrical current is applied to the body to deliver medication or other substances into the tissues. This process can be used to treat various conditions, such as inflammation, pain, and muscle spasms. Unlike desincrustation, iontophoresis, and cataphoresis, which involve the movement of substances in the opposite direction, anaphoresis specifically refers to the movement of liquids from the negative to the positive pole.
