In a practical machine the power output is the power input?
In any practical machine, the power output is less than the power input. In other words, the efficiency of real machines is less than 1.smaller thanalways
The ratio of output power to input power in percent is called a conductivity b efficiency c work d horsepower?
B.) efficiency
Unit of power used mainly in the US?
This depends on the situation. The main power unit used for electric power output is generally the Watt (W), while the main power unit used for mechanical power output is often the horsepower (hp).
How does the scientific use of the word efficiency differ from the everyday use of the word?
Energy is scientifically defined as the ability to do work, and power as the rate at which work is done, or the rate at which work is expended.
The maximum power output of an engine is usually given in units called?
It's given in the units called: BHP=Brake Horse Power
What are the limitations of power supply?
Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.
How do you measure the power input and power output for the step-up transformer?
Power input to a transformer = (voltage across the primary winding) x (current through the primary)Power output = (voltage across the secondary winding) x (current through the secondary)It doesn't matter whether the transformer is used in step-up, step-down or simple isolation.
A receiver requires 10nW as input power if all the system losses add up to 50dB then how much power is required from the source?
here, the power required by the receiver is the output power and that required from the source is input power. Gain in dB=10 log(output power/input power) we have, loss in dB = -gain in dB = 10 log(input power/output power) or, 50 = 10 log(input power/10nW) or, anti-log(5) = input power/10 nW so the power required from the source is antilog(5)*10nW = 1 mW
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
Is ups input or output device?
UPS is Uninterruptable Power Supply. It is neither input not output. It supplies electrical power to a computer when the main electrical supply is interrupted. It does not handle data in any way.
What is the name of energy amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
Is power supply input or output devices?
Output - because it is outputting power to the rest of the device
What does the power relatio0nship state on a transformer?
power in, and power out--input and output.
What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
Why is output dc higher than input ac?
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
