On a 120 v circuit at 7.5 amperes, the power is 120x7.5 watts, 900 watts, and that is the case all the time at every instant the current is flowing.
Over time more and more energy is used, and energy is measured in watt-seconds, also known as Joules, or watt-hours, or kilowatt-hours, also known as Units.
So in one hour 0.9 units of electrical energy are used up. In 5 hours it is 4.5 units.

How do you calculate watts on your electricity bill?
Your are paying for the work of the electric power company and that is power in kilowatts times time in hours. You pay for "kilowatthours".
Electric energy usage on your electric bill is measured how?
Electric energy is measure in Units which are kilowatt-hours. Your electricity meter records the usage in Units over the billing period. The meter measures the true power and not the volts times the amps.
What voltage does an electric pancake griddle use?
The electricity used depends on the the size of the range. An electric stove if used one hour a day can use between 23 and 48 kilowatt hours per month.
How long can it be expected to supply a current of 100mA if a cell supplies a load current of .5 amperes for a period of 20 hours?
100 hours.
What are the limitations of a moddel torch circuit compared to the real actual circuit?
the answer is 3 hours for the limitation as the chemicals in the batteries produce a current of electricity
If 13 A flows for 2 hours in a circuit what is the quantity of electricity that has passed?
Need to know the voltage. Quantity of electricity is expressed in Watts. Watts = amp x volts. Total quantity is expressed in watt/hours.
What does an electric company use to determine how many kilowatt hours of energy are used by a household?
An electricity meter

How many kilowatt-hours of electricity are used by two 60 W electric blankets used for 9 hours?
In each hour two 60W blankets will use 120W. 120W for 9 hours = 1080 W or 1.08 Kilowatts.
How much energy does a TV use and how much it is in dollars?
That will depends on (a) the type of television set, (b) the cost of electricity in your region, and (c) how long you keep it turned on. Take a look at the TV set's electrical specifications - how much it uses in watts. Most electric and electronic devices have a small metal plate that tells that. If it doesn't state the amount of watts, multiply volts x amperes to get watts. Multiply that by the number of hours you want to have it turned on, to get kilowatt-hours. Take a look at an electric bill, and divide the total amount by the number of kWh spent, to get an estimate of the cost per kWh.
