2008/5/18-23 [Science/Battery] UID:49997 Activity:low | 5/18 I'm looking for a good rechargeable AA battery system. What do you guys
use? I'm thinking of getting a bunch of AA NiMH and a really good
charger that can do a full drain/recharge cycle to reduce memory
effect as well as battery tender since NiMH seems to lose 10% charge
per week, or AA Li-Ion with normal chargers. What do you guys think?

2007/11/9-12 [Science/GlobalWarming, Science/Electric] UID:48594 Activity:nil | 11/9 this new fujitsu technology of monitors on standby
that consumes no power is awesome! go nippon!
\_ I invented that technology long time ago. Go finger power!
\_ huh are you sure? I suspect that modern monitors consume
power even when off, due to the big capacitors in the
voltage transformer. this is true of a lot of consumer

2006/3/5-8 [Science/Electric] UID:42101 Activity:low | 3/5 If an appliance is 220V, can I get an adapter or something for it
because I have 120V? Thanks.
\_ A transformer, yes.
\_ I had a similar problem. You need to be very careful about
the actual wattage of your appliance. A transformer that withstands
large wattage tend to be very very big (size of couple bricks and

2006/3/1 [Science/Electric] UID:42041 Activity:moderate | 3/1 Say I have a circuit breaker that says 20A. How many watts can I load
on it before it pops? I'm asking because every time I have a space
heater (1500W) and hair dryer (1850W) on, the circuit breaker pops.
\_ P = VI where P is power in watts, V is voltage in volts, I is current
in amps (A). Wall socket voltage is a max of 120V in the USA and is
220V-240V in some places elsewhere. Can you figure it out now or do

2005/9/3-5 [Science/Electric, Consumer/PDA] UID:39477 Activity:moderate | 9/3 I have AC adaptors for my cell phone and PDA that say the input
should be 120VAC. If I try to use them in Europe where the voltage
is 220V, will I fry my PDA and cell? Obviously, I'll have to use
a plug adaptor to plug them in.
\_ Yes, they will fry. Get a transformer that goes 220V -> 110V.

2005/7/21-22 [Science/Electric] UID:38746 Activity:moderate | 7/20 I have a 12V fan that takes 10W. If I power it using a 2000mA
battery, how long does it take? Basically I don't have a good
clue on the relationship between wattage, amp, and voltage. Thanks!
\_ V = IR and P = VI. Didn't you take physics?
\_ You probably have a 2000mAh battery. That's 2000 milli-amp hours.
Given that, you should be able to figure out how long the

Do you need a special adapter/voltage controller or can you simply match
the voltage requirements and trickle charge it? -scottyg

2012/5/16-7/20 [Politics/Foreign/Europe] UID:54390 Activity:nil | 5/16 Can anyone tell me what Greece is hoping for by rejecting austerity?
From here it seems like the austerity is a pretty generous attempt
to keep Greece from imploding entirely. Are they hoping the
Germans will put them on eternal state welfare, or what?
Also, why would an outright default mean they must leave the Euro?
Is it just that they won't be able to pay basic gvmt services
