Wed follow the smooth-spinning hands of the clock. From my High School Electrical Class teacher: ALL wires contain smoke. Im overwhelmed by all these comments. Not one of them is under 1.0 amp. Is there a way to tell amperage from the batteries required? Yes, sure, other and better and more useful acts were possible, but only if we knew in advance exactly how much time we had to kill, and where, and under which circumstances. Hi this might probably be reaching you late but the receptacle female has a positive center and a negative surrounding while the male will have some gaps along its metal shaft. V = 8.7 volts, To calculate the value of parallel resistors: These type of appliences never have removable powercords so thought is required prior. During the 1980s, Uniden grew to become the world's largest manufacturer of cordless telephones in addition to television satellite equipment, mobile radios, advanced marine electronics and radio scanners (the latter under BearCat brand). 200+ bought in past month. Uniden. its that simple if someone understands the math then please do the problem and share it w those of us who just dont. Perhaps call the likes of APC who make reliable units for home and business and ask them for recommendations or an electrician. Some sites that explain about UPS and Conditioning. If there are only two resistors you can use: Rp=(R1*R2)/(R1+R2) Reread the article and try to follow the examples, check other websites as well if you really want to understand this it just takes time and maybe even somebody in person to show you if you happen to know somebody that is good with this stuff in your neighborhood or your family. -AC Input: 100 ~ 240V 50 ~ 60Hz A good magnifying glass is a necessity for me!
