Answer:
The frequency of the alternating current is 50 Hertz
Explanation:
Step 1 : Write down the formula for getting frequency.
f = 1/T
Where :
f = frequency in Hertz.
T = Period in seconds.
Period is the time taken to complete one oscillation.
Step 2: Analyze the question.
Since the direction changes after every 0.01 second, it takes (2 × 0.01) seconds to come back to the same position.
Therefore it takes 0.02 seconds to complete one oscillation.
Step 3 : Calculate the frequency from the formula.
f = 1/T
f = 1/0.02 = 50 Hertz.
