What about the power loss if the area of the conductor size is doubled?
If the area of the conductor is doubled, the resistance of the conductor decreases, since resistance is inversely proportional to the cross-sectional area. This reduction in resistance leads to lower power loss, as power loss in a conductor is given by the formula ( P = I^2 R ), where ( P ) is power loss, ( I ) is the current, and ( R ) is resistance. Therefore, with a smaller resistance from the increased area, the power loss will be significantly reduced for the same current.
What does dB equals to?
dB (decibel) is a logarithmic measure of the ratio of two power values, for example, two signal strengths. This is often used for power gain or power loss. For example, a loss of 10 dB means that the signal degrades by a factor of 10, a loss of 20 dB means that the signal degrades by a factor of 100, and a loss of 30 dB means that the signal degrades by a factor of 1000.
What Equation is used to determine power loss?
Power (Joules) = the square root of the voltage squared divided by the resistance
Why the corrosion rate expressed in penetration rate is more useful than that expressed in the rate of metal loss per unit area?
In most cases you'd be concerned with loss of strength of an item due to reduction in thickness or in cross section area rather than with how much metal you've lost (weightwise) from the whole of the item surface. It is easy to convert from one to the other though. The imperial unit of mpy (mils per year) equates to a penetration rate of about ten atom spacings per hour :)
How is loss ratio determined?
The loss ratio is determined by dividing the total losses incurred by an insurance company by the total premiums earned during a specific period. It is expressed as a percentage and reflects the proportion of premiums that are paid out in claims. A lower loss ratio indicates better profitability for the insurer, while a higher ratio may signal potential issues with underwriting or claims management. This metric is crucial for assessing the financial health of an insurance company.
What is skin effect in power system?
DEFINITION: Nonuniform density of current due to its characteristic to flow more at the surface of the conductor than that of the other section of the conductor called Skin Effect in power system.EFFECT: Due to the skin effect, whole section of the conductor can not be utilized properly. Moreover, skin effect causes increment in effective resistance of the conductor and in power loss.
What is the power loss in watts of a conductor that carries 24Ampere and has voltage drop of 7.2Volts?
Power = voltage times current 7.2 volts * 24 amperes = 172.8 watts
What is the power loss In a conductor for a 120 v circuit that has a 3 percent voltage drop and carries a flow of 22 Amps?
2640
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
What is conductor loss?
Conductor loss refers to the energy dissipated as heat in a material due to the flow of electric current. It is caused by the resistance of the conductor and is proportional to the square of the current flowing through it. This loss results in decreased efficiency in electrical systems and can lead to overheating if not properly managed.
Corona loss is less when the shape of the conductor is?
Circular
Resistance to the flow of electrons in a conductor causes a loss of?
Energy as heat
How Hollow conductor is used to reduce corona loss how does it reduce the loss?
to have large diameter without increasing its weight.
Can cat5 cable be used FOR SPEAKER WIRING?
No. The conductor size is way too small. The loss of power to the speaker would be huge, and a decent-sized amp could easily overheat the wires. Bad idea.
Why no power loss in pure inductance?
An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R
Which of these is encountered by the electrons while flowing through a conductor?
Electrons encounter resistance while flowing through a conductor, leading to energy loss in the form of heat.
Is thinsulate a conductor?
No, Thinsulate is not a conductor. Thinsulate is a type of synthetic thermal insulation material that is designed to trap heat and keep the body warm by minimizing heat loss.
