10. what is the fundamental frequency of this ac sine wave?\na. 4 hz\nb. 8 hz\nc. depends on the harmonic frequency\nd. depends on the harmonic number\n0 v\n1 second

Answer

Explanation:

Step1: Determine number of cycles

Count the number of complete sine - wave cycles in 1 second. From the graph, there are 4 complete cycles in 1 second.

Step2: Calculate fundamental frequency

The fundamental frequency (f) is the number of cycles per second. Using the formula (f=\frac{n}{t}), where (n) is the number of cycles and (t) is the time in seconds. Here, (n = 4) and (t=1) second, so (f = 4\ Hz).

Answer:

A. 4 Hz
