What is the relationship between time and energy consumption?
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
What is the formula and derived unit of power?
Power = energy / time. Therefore, the derived unit is joules / second, commonly known as the watt.
How is the amount of power calculated?
Power is defined as Work divided by Time. Typically, work is caculated using in Joules and Time in seconds. 1 Joule per second is 1 Watt, the unit of power in the International System of Units.
How many joules of work can a quarter - horsepower air conditioning unit perform in ten minutes?
Convert to compatible units: convert horse-power to watts, and minutes to seconds. Then use the formula: work = power x time.
What is the equation for energy transferred by an electrical appliance?
Energy = power x time. If power is in watts, and time in seconds, energy will be in joules.
What is power and what is the formula?
Power = energy / time. Therefore, the derived unit is joules / second, commonly known as the watt.
How much work is done using a 60-watt light bulb for 1 hour?
In terms of joules, the answer is 216,000 joules. First, you must convert 1 hour to seconds. 1 hr = 60 mins 60 mins = 3,600 seconds The formula for finding power can also be used to find work if power and time are provided. Power = Work/Time 60 watts =work/3,600 seconds To find this, multiply 3,600 by 60 3,600 X 60 = 216,000 The unit for work is joules, so the answer is 216,000 joules.use the power formula
What formula is e equals pt?
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
How are work energy and power related?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time
What is one way of expressing the formula for power?
Power is the amount of energy used per unit of time. In the SI system its units are Watts = Joules per second.
What is power's formula?
In very general terms, power is work (or energy, same units) per unit time. In SI units, power is measured in watts, which are joules per second.
How are work energy and power?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
How energy and work and power related?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time
What is the relationship between time and energy consumption?
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
What is the difference between a radio waves power and its energy?
Power, in all situations is the rate of change of energy. If the power is constant, it can be found using the formula, "Power = Energy Used / Time taken". So, the power of a radio wave (in watts) is equal to the amount of energy it transmits (in joules) per second.In symbols:P = E/t
What does power times time equal?
Power is defined as energy per unit time or Joules per second if you use SI units. This means that multiplying power by time leaves Joules, or energy. Power times time = energy
