The formula is volts times amps equals watts, or watts divided by volts equals amps.
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
The formula for finding mechanical advantage is MA = output force / input force. It represents the ratio of the output force to the input force in a simple machine.

Efficiency is typically calculated as the ratio of actual output to maximum possible output, expressed as a percentage. The formula for efficiency is: Efficiency = (Actual output / Maximum possible output) * 100%.
Its fairly self explanatory, put the input IN then check the output at the OUTPUT.
Productivity is the measure of the output achieved divided by input required.
Achieve large and lasting increase output the economy must achieve increase capcity utilization
To calculate the voltage needed to achieve 800 watts, you can use the formula: Wattage = Voltage x Amperage. If we assume a standard power supply with an amperage of 10A, then the voltage required would be 80V (800W = 80V x 10A). Make sure your power supply can handle this output to safely achieve 800 watts.
Work Output=Resistance X Distance
