# How many amps are needed to efficiently run a dishwasher?

# How many amps are needed to efficiently run a refrigerator?

Answer .
If you are talking about a certain kind or brand, look at the label inside the door. The label will tell you how many amps this unit will need. However all residen…tial refrigerators will run on a 15 amp dedicated circuit or be fine plugged into a regular 20 amp appliance circuit (which is required in kitchens). I have a large side by side unit and it only draws 6.6 amps max. Note that the starting current of an induction motor will be higher, of course, but will drop and stabilize at a "nominal" level within seconds.

# How many amps are needed to efficiently run a central air conditioner unit?

depends greatly on size usually assessed in tonnage how old the unit is and more

# How many amps extension lead would you need to run a 60Hz pump?

This can not be answered with the information you have given. 60Hz does not relate the the current draw so wire size can not be calculated.

# How many amps are needed to efficiently run a freezer?

The wattage and the voltage are required for this. Divide watts by volts this will give you the amperage

# How many amps are needed to run a light bulb?

amps equals watts divided by volts.

# Do you need to run an amp with subwoofers?

Yes. Most head units only put out about 15-20 watts RMS, you need more than that to properly power a subwoofer. Ignore peak ratings, only use RMS ratings to match everything… together.

# How many amps do you need to run a 1 hp electric motor?

One hp is about 750 watts. Power divided by volts equals amps. 750/120=6.25 amps. Answer 2 But this answer takes no account of what the voltage is. It makes the assumptio…n that it is 120 volts. But the various mains in Europe run at about 240 volts. And what about other voltages, eg 12 volts from a car battery? You'd need 65 amps in this case - rather like a car starter motor. Answer 3 The conversion from watts to hp is indeed 1hp = 746 watts (as stated above), but no motor is 100% efficient, so you will never actually find a 1hp motor that draws only 746 watts. Real-world 1hp motors draw somewhere between 1,000 and 1,500 watts. Also answer #2 is correct, you need to know volts to calculate amps, but both answers 1 and 2 are only applicable for single phase motors, the formula is different for 3-phase motors. Further complicating things, volts times amps actually equals VA (volt-amperes) not watts. You must multiply VA times power-factor to get true watts. So, to get an accurate answer, you must simply consult the nameplate of the chosen motor where the amps are directly listed. If you need an approximation the following formulae will get you close (they assume 1,200 VA per hp): Single Phase: Amps = 1200 / nameplate volts Three phase: Amps = (1200 / nameplate volts) / 1.73

# How many watts do you need to run a 1.1 amp fridge?

Your refrigerator is an AC induction motor. It will draw constant current whenever it is on (after starting which is much higher). However the power that it consumes depends o…n the torque on the motor's shaft, which in the case of your refrigerator depends on the temperature difference between your freezer and the radiator coils on the back or bottom of the fridge. As time goes on, dust collects on these coils and power consumption goes up. The correct answer to this question is 'some fraction of 120 volts * 1.1 amps = 132 watts or less.' The rest of the 1.1 amps of current represents energy which is borrowed from the line and returned to it at a different time during the AC cycle. The ratio between current*voltage and actual power consumed is referred to as power factor. Some devices like lights and heaters have a power factor very close to 1 because they do not borrow power from the line. Induction motors and transformers have power factors lower than 1.

# How many amps are needed to run an oven?

It depends on the power of the oven, so you'd need to know that first. Then the current = (power in Watts) / Voltage.
