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).
If the connected load required 10 amps then the wattage load from the battery would be 12 x 10 = 120 watts. Batteries are rated in amp/hours and not watts. This means that if the battery is rated at 500 amp hours it could produce 1 amp for 500 hours, or in our case 10 amps for 50 hours. 12 v battery could be specified as 14 A-h or 14 ampere-hours, which means 14 amps for 1 hour, or 1.4 amps for 10 hours. In â¦ other words it produces less current for a longer time. A 9 watt bulb takes Â¾ amp in theory, so it should last 14/Â¾ hours on that battery, that is 14 x 4 / 3 hours, 18 hours.
