Is tens AC or DC?

Is tens AC or DC? A standard TENS unit typically delivers a low-frequency (<50 Hz) alternating current to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being […]

Do elements in Group 1 gain or lose electrons?

Do elements in Group 1 gain or lose electrons? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions. Most elements in […]

What is the relationship between air pressure and weather?

What is the relationship between air pressure and weather? Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. How pressure affects the wind flow? Air Pressure and Winds Air that moves horizontally between […]
