There are no units mentioned in this question so it's impossible to give it a single answer. "50 Hz" means "50 cycles per second". "50 kHz" means "50,000 cycles per second".
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds
Yes.
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
The Natural frequency is the frequency at which Resonance(maximum amplitude) occurs.
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
50 Hz as per the info available from their official website
Frequency = 1/0.02 = 50 cycles per second or 50 Hertz
frequency of AC current in egyptis 50 c/s
It is concerned with frequency.
Frequency modulation
Frequency swing is nothing but the deviation or the frequency change from the reference frequency
Can be any frequency but is most likely to be the grid frequency - 50/60 Hz.
