Always the perennial third in the national ratings, ABC News president Roone Arledge reformatted the program, relaunching it as World News Tonight on July 10, 1978. Reynolds, who was demoted when the network hired Reasoner, returned as lead anchor, reporting from ABC News' Washington, D.C. bureau.
The correct unit for measuring energy capacity of a battery product is called watt-hours. Watt-hours signifies that a battery can supply an amount of watts for an hour. For example, a 60 watt-hour battery can power a 60 watt light bulb for an hour. The same battery would run a 5W phone for 12 hours and power a 1W LED light bulb for 60 hours.
As one amp equals one hour of use, one watt also equals one hour of use. To do this you can change the amp hour measurement associated with a battery into watt hours. The 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). Thatâs at 100% discharge without pumping in new energy (which means, if you actually do that, youâve likely ruined your battery - you shouldnât go lower than 80% with 50% being better).
