Questions & Step-by-Step Solutions

What is the frequency of an AC signal with a period of 0.02 seconds?
  • Step 1: Understand that frequency (f) is how many times something happens in one second.
  • Step 2: Know that the period (T) is the time it takes for one complete cycle of the signal.
  • Step 3: The relationship between frequency and period is given by the formula: f = 1/T.
  • Step 4: In this case, the period (T) is given as 0.02 seconds.
  • Step 5: Substitute the period into the formula: f = 1/0.02.
  • Step 6: Calculate the frequency: f = 1/0.02 = 50 Hz.
  • Step 7: Conclude that the frequency of the AC signal is 50 Hz.
