QuestionIf I have 78 Watts and a 12V DC battery, how many amps do I have?Community AnswerTo find your amps, in this case, just divide 78W by 12V. You will find that you have 6.5 amps.

QuestionHow many amps are in 1500 watts?DonaganTop AnswererIt depends on the voltage applied.

QuestionIf I have 220 volts and 4500 watts, what is the amperage?DonaganTop AnswererAmperage = wattage Ã· voltage. Restated, current (I) = power (P) Ã· voltage (V).

QuestionDoes 1500 watts equal 13 amps at 120 volts?DonaganTop AnswererAlmost. 1500 watts at 120 volts produces 12.5 amps of current. 13 amps at 120 volts requires 1560 watts of power.

QuestionHow many led fixtures (at 51 watts each) can I put on a 20 amp breaker?Community AnswerAssuming you using 120V of DC power, each bulb would account for roughly 0.425 amps (51 W/120V). This would allow you to put roughly 47 fixtures on one 20 amp breaker.

QuestionTenthousand watts divided by 15,000 volts equals 0.67 amps. Is this correct?DonaganTop AnswererYes.

Question1 amp is how many of what?DonaganTop AnswererAn amp (or ampere) is a unit of electric current. It refers to an amount of electrical charge passing a given point in a circuit over a time period of one second.

QuestionHow many kilowatts is 25 amps equal to?DonaganTop AnswererAs the above article explains, you would have to know how much voltage is being applied, because there is no fixed relationship between power (kilowatts) and current (amps).

QuestionWhat is the function of the capacitor?DonaganTop AnswererA capacitor stores electrical energy for very short periods of time in order to regulate the current in AC circuits.

QuestionI have a 3.5amp motor, 120 volts. What is its wattage?DonaganTop Answerer3.5 amps at 120 volts produces 420 watts of power. Power (watts) equals voltage (volts) multiplied by current (amps).

QuestionDoes 1500 watts equal 13 amps?DonaganTop AnswererIt depends on how much voltage is applied.

QuestionHow do I find out how many amps are in a watt?DonaganTop AnswererThere are no amps in a watt. In other words, there is no direct relationship between the two. Watts measure power (or force). Amps measure current (or electrons). You have to know how much voltage is being applied before you can begin to compare the two measurements, as shown above.

QuestionHow do I know the watt capacity for my thermostat?DonaganTop AnswererBecause they don't actually perform "work," thermostats do not have wattage capacities. They do have voltage ratings, which should be marked on the thermostat or its packaging.

QuestionI have a 20 amp breaker that is intermittent with six 60 watt bulbs and two ceiling fans and six other 60 watt lamps. Is that overloading the 20 amp breaker?Community Answer12 bulbs x 60 watts = 720 watts. 2 ceiling fans wattage (assume 50w each) = 100w. Total = 820 watts. Max power on 120ac x 20amps = 2400 watts, so you are under 820< 2400 watts.

QuestionHow do I determine the ampere of welding machine?Randy RossCommunity AnswerMost welding machines (welders) have a stamp on them indicating the voltage and amp requirements. I have a number of welders and they range from 110220 volt and the smallest will run on a 15amp breaker for light work, the larger welder I have requires 80Amps and 220 volts. If you canâ€™t find a stamp on your welder, then check with the manufacturer for the requirements.

QuestionWhat is power factor (pf)?DonaganTop Answerer"Power factor" is the ratio of "real" (or theoretical) power to "apparent" (or actual) power in an AC circuit. It is a measure of power loss in that circuit.
