Question 49
Alternating Current CircuitsIn the curve above, PQRST represents an alternating voltage of frequency 50 Hz. The time interval between points P and R on the graph is
- A.25s
- B.1/50 s
- C.1/100 s
- D.1/200 s
Show the answer and explanation
Answer: C (1/100 s)
Explanation
One cycle takes 1/50 s. From P to R is half a cycle, so the time is 1/100 s.
