Question

what is meant by high power devices ,low power devices...??
do high power devices means that they consume loads of power and low power consume low power...!!
and what about high frequency and low frequency devies...??

Answer 1

Power is the rate per unit time of energy usage, so, e.g. a 100-W light bulb consumes 100 joules of energy per second while a lower-power 60-W bulb uses 60 joules per second.

Answer 2

For the frequency question, it depends on if you're talking about the frequency of the AC current, or the frequency of oscillation of a mechanical device.

Answer 3

so the high power devises consume large energy than low power devices and that's what form the basis of classifying devices in electronics....amm..ok.
i have considered ac frequency!!
actually now thinking is it possible to be high frequency devices same high power devices or could say they are related in some way...??
thanks!!

Answer 4

High power devices are the devices designed to stand high values of power in a circuit. As power is W=V·I, it is clear to see that high power devices are those designed to work in circuits where a high voltage or a high current or a combination of high current and high voltage occurs. Therefore, it means that certain circuits, due to their characteristics of high voltage and/or high current do require this type of components. Same would apply for frequencies, particularly for active components. Their performance varies with frequency due to many different reasons, basically the speed of mechanisms of generation-recombination and transport of carriers and the physical dimensions of the component that translate into capacitive and inductive effects.
Normally, high frequency devices tend to be of reduced dimensions which also means lower dissipation and hence lower power management

Answer 5

ok..is there any way to connect high frequency with high power !! as:
"high frequency indicates high or significant large energy and high energy indicates large sufficient power as P(power)=joules per second" so somehow must be related with each other...??
