Watts formula

[topramen]

Can anyone help me with the formula for converting amps to watts so that I can determine what's available for heated clothing & accessories? Thank You!!

 

[afterburn]

P = U * I

U = I * R

(Ohm's Law)

EDIT:

P = Power in Watt

U = Voltage in Volt

I = Current in Ampere

R = Resistance in Ohm

I am just going off memory here, so If I screw this up, I am sure someone will gently correct me :lol: ....................

Watts is a measurement of power. Amps is a measurment of current or flow.

Basic formula is Power (in Watts) = Voltage(in Volts) X Current (in Amps)

P=VI

However, its not necessarily that straightforward when trying to determine the answers you want. But this will be close.

....or, you could enter the word "watts" in the Search field, and see almost a dozen threads returned, many of them mentioning the fact you have 120-130-ish available watts (above that needed to run the bike) before you start to overly tax the charging system.

 

[RadioHowie]

volts x amps = watts, so

amps = watts / volts

Watts + Traffic Stop = Riots? No? Well, then nevermind.

No, no... that's

Watts + Traffic Stop = Beating

Beating + Video Camera = Riot

You're thinking about the sequel with Rodney King and the Keystone Cops done back in the early nineties. I'm talking about the original, first done in 1965, starring Marquette Frye and Whitie as the CHP. 'Cept Whitie didn't notice Frye's mama and all of his cousins hanging around when he tried to yank Frye's ass from the car and started whoopin' up on his ass with a baton. Ooooh and when he turned that baton on momma, well the rest as they say, is history.

Any other equations I can solve for anyone? Anyone? Bueller?

Dear Benevolent Dictator,

Thank you so much for the helpful & gentle reminder. At the risk of being thoroughly thrashed & humiliated, I would like to extend the question: If I "have 120-130ish available watts(above that needed to run the bike)", what formula would I use to calculate the available wattage, for example, on my KLR. The bike produces (enter amps here) at (enter rpm's here) which = I don't have a clue to the total wattage produced, wattage needed to run the bike, let alone how much is available for accessories. I'm not too concerned about heated clothing my the FJR; I bought the '04 with the OEM factory installed heater. I'm off to the Search Field...

Thanks again for your help...

Has the smoke cleared... h34r: Is it safe to enter the watts or is it Watts discussion?

Couple of ways to determine what the KLR is putting out.

First, go to the KLR forum and ask the question. Or, is the generator output listed on the Kaw website. (Probably not)

If no, then have an electrically inclined buddy put a clamp-on amp meter on the positive battery cable with the KLR running. See how many amps it reads. Then, find the main fuse and see the rating for it. Simple subtraction will yield the "approximate" left over juice available. For example IIRC, the FJR main fuse is rated at 50 amps. This equals 600 watts power (12 volt X 50 amps). There is however, some extra built in the fuse for starting, surges etc.. FJR has about 500 watts total generator output (41.67 amps)

All the normal disclaimers apply...proceed at your own risk.

No, no... that's

Watts + Traffic Stop = Beating

Beating + Video Camera = Riot

so maybe if the taser had more amps the video would have been shorter?

A typical clamp-on ammeter won't work on a DC circuit.

 

[Geezer]

120 watts divided by 12 volts leaves you with about 10 amps for extra goodies.

Yep, my foible... :blink: need to be in series to measure DC amps.

Back to the cave.
