What is the total kilowatt hours used if a microwave oven operates on 5 amperes of current on a 110-volts circuit for one hour?

Power = (voltage) x (current) = 110 x 5 = 550 watts
If operated at this level for 1 hour, then
Energy = (550 watts) x (1 hour) = 550 watt-hours = 0.55 kilowatt-hour.
Another Answer
As microwave ovens don't operate continuously, but in short bursts, it's not really possible to determine an answer to your question without knowing the frequency and duration of these bursts of energy.

∙ 11y agokilowatt hour is the same as 1000 watt-hours. So using that principle, a 1200 watt microwave consumes 1.2 kWh of power, so in an hour it uses up 1.2 kWh of energy.

How do you Calculate Pumping Cost using Horse Power and also Amp's?
Horse-power: convert that to kilowatt. Multiply by the time in hours you have the pump on, to get kilowatt-hours. Multiply the result by the cost of each kilowatt-hour. (Look at a recent electricity bill - if it doesn't explicitly state the cost per kilowatt-hour, you can divide the total of the bill by the number of kilowatt-hours consumed.)Amperes: You would also need the voltage. If you multiply amperes by volts, you get the power in watts. Divide the result by thousand to get kilowatts. Then continue as above.CommentAs the horsepower quoted for a machine is always its output power, you will need to know the efficiency of the machine in order to determine the input power (in watts), before performing the above calculations. The input power is always higher than the output power. Efficiency varies according to (a) the power rating of the motor, and (2) the actual load it is supplying, and can be less than 80% for smaller motors.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
How many amperes are there in a kilo-ampere?
Since kilo- means one thousand, there are one thousand amperes in a kilo-ampere, and there are 0.001 amperes in a kilo-ampere.
1 kilowatt is equal to how many amperes?
Kilowatts means power P and amperes mean electrical current I. That does not go together. Power is not current. There is nothing equal. 1 kilowatt means 1000 watts. You can make a calculation if you know the voltage V. P = V times I I = P / V = 1000 watts / x volt
What is mva?
In electrical engineering it can be millivolt amperes, unless it's MVA then it is megavolt amperes. Such as in the use of large transformers.
How many watts from a solar panel do you need to power a 6 volt radio?
The power required is(6) times (the amperes of current the radio draws when it operates) watts.
What electrical units do you rate a wind turbine and a power station?
Watts kW = (1 kilowatt = 1000 Watts) MW = (1 megawatt = 1000 kilowatts) GW = (1 giagawatt = 1000 megawatts) Volts Amperes

What is the voltage of microwave with a resistance of 5 ohms and current flowing of 10 amperes?
It looks as if you can use Ohm's Law to calculate this: V=IR (voltage = current x resistance).
A current flow of 15.5 micro amperes is the same as?
15500 nano amperes or .0155 milli amperes or .0000155 amperes
What can you measure with amperes?
Current is measured in amperes. Amperes is also coulombs per second.
What total ampere in 736watts used in 8 hours?
You cannot find ampere from watts (power) and time, alone. To find amperes (electrical current) from power, you also need to know the voltage, then:Current = (Power) / (voltage), or Amperes = Watts / Volts.You can get energy (measured in kilowatt-hour) from the information you have:736 watts is 0.736 kW, then multiply by 8 hr to get 5.888 kWh
What are amperes measured in?
Amperes - they are the unit of current
What measured in amperes?
Amperes - they are the unit of current
How do you measure kilowatt to ampere?
These are three different type of units; the kilowatt hour is a measure of energy, kilowatt a measure of power and the amp a measure of current. or That is an easy one. If you plug a 100 watt bulb into a 110 volt outlet you will draw 0.91 amps. Watts=voltage times Amperes. The draw on the circuit will be 0.1 kiliowatts (1000 watts is one kiliowatt) If you leave this bulb on for ten hours you will have drawn a kiliowatt hour (KWH is power over time) In one hour this bulb will have drawn 0.1 KWH That help?
How Kilowatt to amperes?
The symbol for 'kilowatt' is 'kW', not 'Kw'.The kilowatt is used to measure power, whereas the ampere is used to measure current. These are different quantities, so you cannot simply convert one to the other. It's a little like asking "How do you convert kilometres per hour into newtons per metre?"!However, if you know that the power-rating of a kettle is 3 kW, and the supply voltage is 230 V, then you can find out the resulting current by dividing the power by the voltage. In this example, the current would work out at 13 A.
Is a kVa the same as an amperes?
KVa is not the same as the amperes because KVa is the unit for reactive power while amperes is the unit for current.
