this depends on how much energy you are converting, which is why it is so appropriate to talk about this energy loss in terms of efficiency. The energy efficiency of an AC/DC transformer is, also, dependant on the voltage and current that is running through the system, however numbers as low as 75% and as high as 96% would give a reasonable range of efficeincy. To find out how much energy is lost per second (power) just take the Watts of the circuit (volts x amps, simplified) and just multiply that resulting wattage by 1-efficiency, so in the case of the 96% efficient transformer on a 300Watt circuit, the energy loss is 12 watts. These 12 watts get turned into heat, which is why you frequently find that these little Transformers for your gadgets are warm.
What else can I help you with?
Which is a source of ac current a) a battery b) a generator c) chemical cells wired in series d) chemical cells wired in parallel?
b) a generator. Generators create alternating current (AC) by converting mechanical energy into electrical energy through electromagnetic induction.
How is solar energy stored in the source and how is energy released?
Solar energy is stored in solar panels as direct current (DC) electricity through the photovoltaic effect. This energy can then be stored in batteries or converted to alternating current (AC) electricity for immediate use or to be fed into the grid. When energy is needed, it is released by converting stored electricity back to AC for use in electrical appliances or by using the energy stored in batteries.
Is a hair dryer direct or alternating?
A hair dryer is powered by alternating current (AC) electricity. This type of current allows the hair dryer to function effectively by converting electrical energy into heat and air flow.
Is it energy efficient to leave the window open with the AC on?
Leaving the window open while the AC is on is not energy efficient because it allows cool air from the AC to escape outside, making the AC work harder to maintain the desired temperature. This can lead to higher energy consumption and increased costs. It is recommended to keep windows closed when using the AC to maximize energy efficiency.
Which type of current does a windmill produce?
A windmill typically generates alternating current (AC) when converting kinetic energy from the wind into electrical energy. This is because AC is easier to transmit over long distances compared to direct current (DC).
How much energy is lost in converting AC to DC energy?
how much energy is lost in converting dc energy to ac energy
How much energy is lost in converting DC to AC energy?
how much energy is lost in converting dc energy to ac energy
Is any power lost when converting from dc to ac?
Of course, when we convert dc to ac, we need to feed an electronic circuit using transformers that have a range efficiency between 80 to 90, depends on the iron composition of the frame.
How much energy does an AC unit use on average?
On average, an AC unit uses about 3,000 to 5,000 watts of energy per hour.
Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
Which is a source of ac current a) a battery b) a generator c) chemical cells wired in series d) chemical cells wired in parallel?
b) a generator. Generators create alternating current (AC) by converting mechanical energy into electrical energy through electromagnetic induction.
What is the divice used for converting AC into DC is called?
A rectifier
What important system consisting of diodes in converting ac to dc?
Halfwave or fullwave or polyphase AC to DC?
What AC actually means in AC adapter?
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
How is solar energy stored in the source and how is energy released?
Solar energy is stored in solar panels as direct current (DC) electricity through the photovoltaic effect. This energy can then be stored in batteries or converted to alternating current (AC) electricity for immediate use or to be fed into the grid. When energy is needed, it is released by converting stored electricity back to AC for use in electrical appliances or by using the energy stored in batteries.
Why car shuts off when ac is on?
The AC is taking energy
Is a hair dryer direct or alternating?
A hair dryer is powered by alternating current (AC) electricity. This type of current allows the hair dryer to function effectively by converting electrical energy into heat and air flow.
