Step-by-step solution for: Electricity Worksheet - WordMint
Let’s go through each question one by one and match it to the correct answer from the list.
---
1. Electricity → This is the movement of electrons.
→ Match: N. Movement of electrons
2. A good conductor → Copper is known for conducting electricity well.
→ Match: E. Copper
3. Nonconductor is also known as → A nonconductor is called an insulator.
→ Match: Q. an insulator
4. Changes AC to DC → A rectifier converts alternating current (AC) to direct current (DC).
→ Match: U. Rectifier
5. Rapid, interrupted current flowing in one direction then in the opposite direction → That’s alternating current (AC).
→ Match: X. Alternating current
6. Unit that measures the pressure or force that pushes electric current forward → That’s voltage, measured in volts.
→ Match: B. Volt
7. Measures the strength of an electric current → Current strength is measured in amperes.
→ Match: W. Ampere
8. Current used for facial and scalp treatments is measured in → These use very small currents — milliamperes.
→ Match: D. Milliampere
9. Measures the resistance of an electric current → Resistance is measured in ohms.
→ Match: G. Ohm
10. Prevents excessive current from passing through a circuit → That’s what a fuse does.
→ Match: S. Fuse
11. All electrical appliances you use should be .. → For safety, they should be UL certified.
→ Match: J. UL certified
12. Currents used in electrical facial and scalp treatments → These are called modalities in cosmetology.
→ Match: V. Modalities
13. Positive electrode → That’s the anode.
→ Match: R. Anode
14. Negative electrode → That’s the cathode.
→ Match: H. Cathode
15. Form of anaphoresis; Used to treat acne, milia, and comedones → That’s deincrustation.
→ Match: F. Deincrustation
16. Process of infusing water-soluble products into the skin with the use of an electric current → That’s iontophoresis.
→ Match: M. Iontophoresis
17. Extremely low level of electricity that mirrors the body’s natural electrical impulses → That’s microcurrent.
→ Match: C. Microcurrent
18. Also known as violet ray → That’s Tesla high-frequency current.
→ Match: T. Tesla high-frequency current
19. The distance between two successive peaks of electromagnetic waves → That’s wavelength.
→ Match: I. Wavelength
20. Visible light makes up how much of natural sunlight → About 60%.
→ Match: L. 60%
21. Invisible infrared light makes up how much of natural sunlight → About 35%.
→ Match: A. 35%
22. Invisible ultraviolet light makes up how much of natural sunlight? → About 5%.
→ Match: P. 5%
23. The shortest and least penetrating light of the spectrum → Ultraviolet light has short waves and doesn’t penetrate deeply.
→ Match: K. ultraviolet light
24. Substances that speed up chemical reactions → Those are catalysts.
→ Match: O. Catalysts
