In addition to classes, students will also need to complete hands-on work in dental practice labs and shadow a professional for a set number of hours to complete their degree program. A bachelor's degree in dental hygiene will be more than sufficient for a position as a dental assistant.he education requirements for dental assistants vary by state. In some states, dentists may hire untrained individuals and teach them the tasks of the dental assistant. Other states require assistants to complete a formal training program.
Amp Hours (AH) - The volume of electricity, capacity. A batteryâs storage capacity is measured in amps or amp (ampere) hours. One amp equals one hour of use without recharging-or, in practical terms, how long you can use power on a dark, rainy day.he equation for finding how many watt hours are available in a battery when the amp hours are known is voltage x amp hours. For instance, a 12 volt 105 amp hour (AH) battery can supply 1260 watt hours (12 volts x 105 amp hours =1260 watt hours).
The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle. The Wh capcity can be approximated from the Ahr capacity by multiplying the AH capcity by the nominal (or, if known, time average) battery voltage. A more accurate approach takes into account the variation of voltage by integrating the AH capcity x V(t) over the the time of the charging cycle.
