I just stopped using the LM3914, and now use a quad comparator (LM339) with a simple voltage divider. It's a little bulkier but at least it works.
Ohms Law! E=IR Voltage equals current times resistance. Get out the old calculator...
Volts - album - was created on 1997-11-18.
Ranges can be a verb, as in the sentence, "The age of the girls in the class ranges from 18 to 24."
12 volts is less of power than 18 volts drill
V=R I then, V = 10 + 8 = 18V, R=2Ohm, I=V/R=18/2=9A
You can't compare volts and amps in this context. If you mean 18 Volts vs. 14 Volts then the 18 Volt tool will provide more power for the job.
36 is to 12 as 18 is to 24.
Just get out your trusty calculator and multiply 120 times 18.
12 volts on the low end, 18 volts on the high end.
10 volts minimum,18 max.
Volts x Amps = Watts, divide with 1000 and you get kilowatts.
18 Volts.
