Well VHF is more for long distance and has a longer wavelength. So, it would logically require more power. UHF is more line of sight and has good in building penetration and doesnt require the transmit power that VHF would require.
For a purely resistive load with a unity power factor, 9.41 kVA would equal 9.41 kW. However some equipment such as a motor will have a power factor less than 1. If the power factor is 0.8 then 9.41 kVA would equal 9.41 x 0.8 kW.
Power factor correction is a process that has to do with managing the essential traits of electric loads that are used to create a power factor of less than one.
Transformers are used with tools that operate on less than 'mains' voltage.
Less cost effective than grid power, produce carbon emissions locally rather than further away.

FM radio station transmit power in kW, while microwave radio only transmit in 1+ W max. New microwave radio transmit power less than 1W.
That depends on the relative sizes of the gear shafts used to transmit power from the motor to the wheel. For instance, if they were the same size, and no gears in between, then the wheel would rotate 400 times a minute (RPM), which is 6.66 times a second. But usually gears transmit power in such a way that the wheel rotates slower than the motor (less RPM) but with more power.
contactor are usually bulkier than relays .they are usually used for supplying power to heavy current using equipment eg industrial motors etc.relays are generally used in control panels supplying power to less current using control equipment
Very few bulbs take exactly the nominal power. Because of manufacturing variations they can take up to 5% less or more than stated. It could also be due to measurement inaccuracy in the measuring equipment used for this measurement.
Yes the fiber glass is a bit more flexible.
Nobody. If they have more power, then they cannot have less. And if they have less, they cannot have more. So nobody can have more AND less.
Watts refers to the power used or the power output of a device. There are two common usages in audio and video applications, audio power output and power used by equipment. Audio power output: Measured in watts but there are several different methods to describe it. RMS power is regarded as the most reliable measure of the output capability of am amplifier. However, peak power output is exactly double the RMS value. To make it more complex, peak music power output is also quoted. It's a value that is an estimation of power based on less than scientific calculations. Normally, it is double the peak power rating. Power consumption Power consumption varies. The average consumption is often far less than the peak consumption, as equipment turns on, or a motor starts up for example. The power rating on equipment is often shown for peak power.
Laptop processors are designed to use less power and create less heat than desktop processors laptop processors are used less power.
no no it is not
A PC uses less power than a TV
100 cm3 is less than a gallon.
The equipment with the "n" designation can transmit data at twice the speed of "g" routers and is more than five times as fast as "b" wireless routers.
