240. Standard for EU
Current= Volage/Resistance
since the iron loss depends only on the volage and frequency,the supply volage is 230v ac.Hence iron loss is always constant
different method are available for converting voice signal to volage ......one method is sence presure variation from the out put of mic by using presure tranducer ..out of transducer should be a volage .this volage is amplified by using amplifier cicuit and it amplified signal or volge is store in to battery or other storig device.......
action potational. volage change, threshold etc
10 Hz 10 Hz
The first harmonic of 220 Hz is 220 Hz, the second harmonic is 440 Hz, and the third harmonic is 660 Hz. These harmonics are multiples of the fundamental frequency (220 Hz) that create different pitches when combined.
Bulgaria became Bulgaria in the year 681.
Bulgaria in Spanish is Bulgaria, or Republica de Bulgaria.
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
mega = 1,000,000 1MHz = 1,000,000 Hz.
There is no inherent disadvantage of 50 Hz compared with 60 Hz, bearing in mind that systems that run at 50 Hz are designed to run at 50 Hz.
The periods for waves with frequencies of 1 Hz, 5 Hz, 10 Hz, and 20 Hz are 1 second, 0.2 seconds, 0.1 seconds, and 0.05 seconds, respectively. Period is the inverse of frequency, so to calculate the period, you take the reciprocal of the frequency.
