What is energy formula?
For the potential energy the formula is. P.E. = mgh. Unit. The SI unit of energy is joules (J), which is named in honour of James Prescott Joule.
What is the formula you use to calculate power?
Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
What is current formula?
The relationship between current and resistance in an electric circuit. Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R.
How do we calculate efficiency?
Calculating energy efficiencies Calculate the percentage of the input energy ending up in the desired output and you have the efficiency: efficiency = energyoutenergyin × 100 %.
How do we calculate time?
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
What is the formula for efficiency of a machine?
To calculate the efficiency of a machine, divide the output work by the input work and multiply the result by 100 percent.
What is the formula for calculating energy efficiency?
Energy efficiency is calculated by dividing the energy obtained (useful energy or energy output) by the initial energy (energy input).
How do you calculate the efficiency of a ramp?
The efficiency of the ramp tells us what fraction of the input energy (kinetic energy) does useful work (lifting). If you have initial kinetic energy E=12mv2 then on a frictionless ramp you should be able to reach a height h=v22g. For an initial velocity of 8.
How do you calculate efficiency example?
For example, if you put 100 Joules of energy into a machine, and got 50 Joules back out (and the other 50 Joules was wasted by the machine), you would have 50% efficiency. So, if you put in 50 Joules and got 45 Joules back, you would have: % Efficiency = (45 J) / (50 J) * 100% = ?
How do you calculate power output?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W . You can also use our power calculator to find work - simply insert the values of power and time.
What is efficiency example?
Efficiency is defined as the ability to produce something with a minimum amount of effort. An example of efficiency is a reduction in the number of workers needed to make a car. ... The efficiency of this loudspeaker is 40%.
What is formula for productivity?
The productivity formula is simple: Productivity = Output / Input. Another way to look at it is: Productivity = Value of Work / Hours Worked. Output can be measured in units, whereas value of work is typically measured in dollars.
What is the SI unit of efficiency?
The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units. In SI-units it is joule per joule, but often also expressed as joule/kilowatt hour or British thermal units/kWh.
Why Efficiency has no unit?
We express efficiency as a percentage. ... In other words, it has no units (Percent is NOT a unit.). If you look at the efficiency equation at the right, you can see why efficiency has no units. Notice that the SI unit for work out is Joules, which is the same as the SI unit for work in.
