How many amperes use an electric heater?
The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).
Does a 100 watt dc motor put out 100 watts in reverse?
Yes it can but it is a bit more complicated then that. The motor that is rated at 100 Watts will draw 100 watts electrical power, but will only output 70-80% of that in mechanical power. So in order to get 100 watts back out you would have to put in ~120 watts of mechanical power to get 100 watts electrical back out.
Input 100-240 V 50-60Hz 1.5A 1 5A what is power in watts?
100v at 1A is 100 watts, 240 v 5A is 1200 watts. The other numbers give intermediate amounts of watts.
1hp equals how many watts in mechanical calculation?
In mechanical calculations, 1 horsepower (hp) is equivalent to approximately 745.7 watts. This conversion factor is commonly used to calculate power output in different units.
How does horsepower relate to Watts and power?
Horsepower is seldom used when referring to electricity because it has a couple different definitions i.e. Mechanical Horsepower, Metric Horsepower, Electrical Horsepower etc. In general 1 Mechanical Horsepower would = 745.6999 Watts.
How do you calculate electrical efficiency?
Electrical efficiency is calculated by dividing the useful output power (in watts) by the input power (in watts) and multiplying by 100 to get a percentage. The formula is: Efficiency = (Useful output power / Input power) * 100. The higher the percentage of efficiency, the more effective the electrical system is at converting input power into useful output power.
When a cyclist expends 1000 watts of power to deliver mechanical energy to her bicycle at a rate of 100 watts what is the efficiency of her body?
The efficiency of the cyclist's body is 10% in this scenario. This is calculated by dividing the useful power output (100 watts) by the total power input (1000 watts) and multiplying by 100 to get the percentage.
If a 13 dB gain antenna has 2 watts of power at the input what is the effective radiated power?
40 watts
What is percentage of efficiency if a power supply produces a 0.5 Watts output with an input of 0.6 Watts?
You need to divide the output power by the input power. If you want to express that as a percentage, you would also multiply this result by 100.
What is amperage input of transformer on 208 3 phase?
The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.
What is the power output of the human heart?
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
What is the efficiency of a dc generator that requires 200 watts of energy to supply 160 watts of output power?
The efficiency of a DC generator can be calculated using the formula: Efficiency (%) = (Output Power / Input Power) × 100. In this case, the input power is 200 watts and the output power is 160 watts. Thus, the efficiency is (160 W / 200 W) × 100 = 80%. This means the generator operates at 80% efficiency.
How many amperes use an electric heater?
The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).
Prove 1 horsepower equals 746 watts?
There is no proof. 1 mechanical horse power is simply defined as 745.7 watts. Period.
How do you calculate power dissipated by an IC?
It is very critical to never exceed the input voltage of an IC to begin with. To calculate the power dissipation ( in watts) VxI (Voltage x Current) will give you power in watts.
Electrical power is expressed in watts or?
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
What is the most accurate watts to temperature calculator available for determining heat output in a given system?
The most accurate watts to temperature calculator for determining heat output in a system is typically a thermal modeling software program, such as ANSYS or COMSOL. These programs use complex algorithms and simulations to accurately calculate the temperature rise based on the power input (in watts) and the system's thermal properties.
