Best Answer

It depends on the voltage source.

watts = voltage * voltage / resistance

and

amps = voltage / resistance

example 1:

To produce 600W from a 120V source, you need a resistor of size 120V*120V/600W = 24 Ohm. This would pull 120V/24 Ohm = 5 amps.

example 2:

To produce 600W from a 240V source, you need a resistor of size 240V*240V/600W = 96 Ohm. This would pull 240V/96 Ohm = 2.5 amps.

How many amps needed for a 600 watt floodlight?

Watts = Volts x Amps for an incandescant bulb. So Amps = 600/120.

How many heaters can you install with amps V?

Five amps is 600 watts on 120 v and 1200 watts on 240 v.


How many watts is 5 amps?

600 This depends on the voltage Voltage x Amps = Watts ex. At 120 volts 5 amps WILL BE 600 watts But at 110 Volts (Some house voltage), it will be 550 watts And at 277 Volt (commercial-Industrial Voltage), it would be 1385 Watts If you know Watts (Like a 75w Incandescent Lamp) and the Voltage: Watts / Volts = Amps So 75w / 120v = 0.625a The last would be Watts / Amps = Volts 600w / 5a = 120v


What is least expensive to run a heater with 750 watts and 7.1 amps or 600 watts and 12.5 amps?

The heater with 750 watts and 7.1 amps is less expensive to run. This is because it has a lower amperage, meaning it requires less electric current to operate. The 600-watt heater with 12.5 amps requires a higher electric current, which could translate to higher electricity costs.


How many amps does a 12 volt 600 watt transformer use at 120 volts?

A transformer does not use, it transforms voltage from one value to another. The output amperage is governed by the connected load. If the load wattage is higher than the wattage rating of the transformer then either the primary or secondary fuse will blow or the transformer will burn up if the fusing is of the wrong sizing. The maximum primary amperage can be found by using the following equation, Amps = Watts/Volts, A = W/E = 600/120 = 5 amps. The same equation is used for the calculating the maximum secondary amperage, A = W/E = 600/12 = 50 amps.


1 A microwave oven uses a 115 V electrical source and produces 600 Watts of power How many amps does it require?

P=UxI so I=P/U so 600/115=5.21 A ignoring losses


How many watts does a 54 inch television have?

you have to know how much voltage it is plugged into and how many amps it consumes. voltage x amps = watts. Look on the electrical plate on the back of the TV. for example in the US it might be 120 volts x 5 amps = 600 watts or .6 kilowatt hour (about 6 cents per hour). This tells you how much electricity the TV uses, not how many it has.

What size of 12v transformer will run 600watts?

Amps * Volts = Watts Amps * 12 = 600 600/12 = Amps = 50 amps You would need a reserve capacity, so I'd go somewhere between 60 or 100 Amp rated transformer. Transformers are rated in volt-amps which is usually calculated the same as watts. But the term "watts" technically does not apply to transformers. So you need a 600 volt-amp transformer or, as Redbeard has suggested, you need an 800 or 1000 volt-amp transformer. That's a lot of amps for a 12 volt system so I recommend you double check your requirements. You will need a #2 gauge wire if your requirements are correct.


How many amps does a small microwave use?

13 amps should be a dedicated outlet since one outlet has a maximum capacity of 15 amps <<>> If the supply voltage is 120 volts then the amperage is I = W/E. Amps = Watts/Volts = 1450/120 = 12.08 amps.


How many watt in 5 amp switch normally use in home?

The switch will use no wattage whatsoever. The load on that switch is what uses power. If you know the load is 5 amps then 5 amps at 120 volts is 600 watts.
