Codyhtml Posted August 26, 2005 Report Share Posted August 26, 2005 I am a little confused about these if somebody could define them for me and help me understand the difference i would be glad Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted August 27, 2005 Report Share Posted August 27, 2005 Potential differance Is the differance in charge between two conductors, measured in volts - an analogy would be the preasure differance between a balloon and the outside air preasure.CurrentThe amout of electrons (charge) passing through a conductor per second measured in amperes amps for short an analogy would be the flow of air in the pipe connected to the balloon.WattsThe amount of power dissipated per in in jouls per second also measured in watts, this is equal to potential differance * current.

Codyhtml Posted August 27, 2005 Author Report Share Posted August 27, 2005 still confusing :'( Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted August 28, 2005 Report Share Posted August 28, 2005 Ya confused try this 536 watts = 1 horse Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted August 28, 2005 Report Share Posted August 28, 2005 Sorry about that just had to say it. volts * (times) amps = wattsand if you had a 110volt 100 watt light bulb it would draw how many amps110 /100 =1.1 amps 110 devided by 100 equals 1.1 Quote Link to comment Share on other sites More sharing options...
Staigen Posted August 28, 2005 Report Share Posted August 28, 2005 and if you had a 110volt 100 Quote Link to comment Share on other sites More sharing options...
Codyhtml Posted August 31, 2005 Author Report Share Posted August 31, 2005 well what i understand in amps is how much current is being drawn through the wire right?and what i've heard is watts is what is being emited is that right?but what is realy confusing is how some power suplies such as inverters for your car to make mains and like solor cellls and stuff are rated in watts why would the power suply care how much current reaches it from what it put out? to a certin extent i mean you can't have like a 100watt light bulb conected to a solor cell or somthing rated for 5 watts dosent work that way but i still don't get why it is in watts not amps?

audioguru Posted August 31, 2005 Report Share Posted August 31, 2005 Electrical power that is being used is measured in Watts.A 100V/1A lightbulb or heater uses 100 Watts.A 1V/100A lightbulb or heater uses 100 Watts.A 10V/10A lightbulb or heater uses 100 Watts.They all produce about the same amount of light or heat even though their voltage and current has changed a lot.Everyone knows that a 100W lightbulb is bright, 60W is medium and 40W is not very bright.Nobody knows the brightness of a 40A lightbulb without also knowing its voltage then multiplying them into Watts. ;DUnderstand now?

Guest Alun Posted August 31, 2005 Report Share Posted August 31, 2005 well what i understand in amps is how much current is being drawn through the wire right?and what i've heard is watts is what is being emited is that right?Watts are the units of power, the amount of energy that's being consumed per second.but what is realy confusing is how some power suplies such as inverters for your car to make mains and like solor cellls and stuff are rated in watts why would the power suply care how much current reaches it from what it put out? to a certin extent i mean you can't have like a 100watt light bulb conected to a solor cell or somthing rated for 5 watts dosent work that way but i still don't get why it is in watts not amps?A 12V 1A power supply is rated for 12W, or 1A at 12V, giving the power output in watts is just a differant way of describing this you could connect a 5W bulb to a 10W cell as long as the load is smaller than the maximum output of the supply you won't have a problem, unless a minimum load is given in the specification.
