What is a 10-20 vdc power source?
A 10-20 vdc power source is a low output power supply used for small devices like battery chargers, notebook computers, and appliances. They use AC power input to convert it into DC power.
If you do work on an abject in one-third the usual time your power output is?
1. If you do work on an object in one-third the usual time, your power output is A) one third the usual power output. B) the usual power output. C) three times the usual power output. D) impossible to predict without additional information. Answer: C
Compared to yesterday you did three times the work in one-third the time To do so your power output must have been?
it would be 9 times yesterday's power output
How do you multiply to the power two thirds?
for example 2 to the power of two thirds, you have to find the percent of two thirds , then use the percent [to the power] then mutipy to the power [like with exponets] then you should get your answer.
When a number is raised to a power what is it called?
The power could then be called an exponent. The number that is being raised to a power is called the base. In the case of 42, the exponent is 2 and the base is 4.
The ratio output power to input power in percent is called?
B. Efficiency
The ratio of output power to input power in percent is called a conductivity b efficiency c work d horsepower?
B.) efficiency
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?
If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
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.
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.
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).
