## Answer

A watt-hour is a measure of watts * time. One watt-hour is the amount of energy used by something drawing one wattbeing used for one hour. The**kilowatt hour**(symbol

**kW·h**,

**kW h**or

**kWh**) is a unit of energy.

Energy delivered by electric utilities is usually expressed and charged for in kWh.

Note that the kWh is the product of power in kilowatts multiplied by time in hours; it is not kW/h.

Also note that watt is the rate at which energy is flowing.

For simplicity it means that a 1000 W device will consume 1 kWh in exactly 1 hour.

Also a 100 W bulb will consume 1 kWh in 10 hours.

(Watt is like speed and kWh is like distance )

### How many watts does a microwave consume in an hour?

Watts are units for measuring the rate of energy
consumption. So it is meaningless to speak of how many watts
something consumes in a length of time. (It would be like asking
how many miles per hour a car drives in an hour.)
Energy consumption may be measured in kilowatt-hours. A typical
microwave consumes 1500 watts, which would be 1.5
kilowatt-hours in one hour.

### How many kilowatt hours - KWh - are used to light a 30 watt light bulb for 1 hour?

A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts.
A kWh or kilowatt-hour is the rate of electrical usage. It is a
measure of kilowatts used per period of time (1 hour). 1 kWh is 1
kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03
kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20
minutes, this lamp would use 1 kWh.

### How many kilowatt hours does a tv use in an hour?

Examine your television set; somewhere at the back, you should
see how much watts it uses. If it doesn't, look for volts and
ampères, and multiply those to get watts. A kilowatt is 1000 watts;
a device that uses 1000 watts will use 1 kWh per hour; one that
uses 100 watts will use 0.1 kWh per hour, etc.

###### Asked in Science

### How long is a kilowatt hour?

A kilowatt hour is not in and of itself a measurement of time.
It is power in watts (more specifically kilowatts) multiplied by
time in hours. A kilowatt is equal to 1000 watts. If a device uses
say 2500 watts for 1 hour, that is equal to 2.5 kilowatt hours. If
that same device is used for 2 hours it is equal to 5 kilowatt
hours.
Right. And it is power multiplied by time, which is energy and
is what you pay for on your inappropriately named "power
consumption" energy bills.
