If the efficiency of a machine increases what would occur?
Then the machine would have a greater output power, or alternately, require less input power.
If you do work on an object in half the time, your power output is?
If you do work on an object in half the your power output is
How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
How does speed affect Power?
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
How much power is required by a 1 horsepower motor?
1 horsepower is the output power - the power produced. The power it uses is more, because no engine is 100% efficient. How much more, depends on the type of engine; an explosion engine (such as one that uses gasoline) is basically a heat engine, with an efficiency of perhaps 1/3; that means that about three times the output power is actually consumed. For an electrical motor, the required electricity will be only a little more than 1 horsepower (about 742 watts running current, more when the motor is getting started).
If the resistance of a load increases will the current increase or decrease?
it increases because increasing load means more output power, more output power means more current
What increase if you use more cells?
the power output increases
How does music change the power output of patients?
It increases their white blood cell count.
What is the basic difference between transistor as an amplifier and a step up transformer?
The output power of an amplifier is greater than its input power, whereas the output power of a transformer is almost the same as its input power. In other words, an amplifier increases acts to increase power, whereas a transformer only increases voltage.
What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
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 does the lumen output change as wattage increases for an MR16 bulb?
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
Which AC input transformer required for 5volt dc output power supply?
It depends on the required output current, load rejection factor, and ripple. Also, efficiency enters into the picture.
How the power is increases in gas turbine by adding fuel?
Very simply, more fuel burned, more power output. This applies to any combustion engine.
How will the armature current and the output power of a dc shunt motors change with increasing load?
With increasing torque load the armature tends to slow down; the motor draws more current to compensate, and if there is armature resistance the back emf generated by the armature falls to allow the increased current to flow, which causes the motor to settle at a lower speed. The mechanical output power is the speed times the torque, and increasing the torque increases the power output provided the speed does not drop much.
White bias-line equation?
An amplifier is what increases a rock band's speaker sound output into a ear splitting experience and small radio signals in a radio until it makes it out to the speaker. A transformer converts AC electricity up or down to a desired level for a required project. Example: A battery charger plugged into a wall socket will transformed to about 18 votls to do the charging. Speaking in technical terms, an amplifier is a device which increases the power of a signal by either increasing the voltage or current or both. Whereas, a Transformer is a device which simply transfers power, i.e., the energy on both input and output is the same. In the case of an amplifier, the output power is higher than the input power. This is because of the power input we give to an amplifier.
It takes the person 5 seconds to move 10 meters What is the power output?
The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.
