Q
Q: What is the frequency of an AC signal with a period of 0.02 seconds?
Solution:
Frequency (f) is the reciprocal of the period (T). Thus, f = 1/T = 1/0.02 s = 50 Hz.
Steps: 7
Show Steps
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.
