The frequency of alternating potential is a measure of how many times the direction of the potential changes in one second. In this case, the frequency is given as 50Hz, which means that the direction of the potential changes 50 times in one second.
Understanding Frequency:
Frequency is a fundamental concept in alternating current (AC) circuits. AC current is characterized by its frequency, which represents the number of cycles or oscillations per second. In the case of an alternating potential, the potential changes its direction periodically, and the number of times it does so in one second is the frequency.
Definition of Frequency:
Frequency is defined as the reciprocal of the time period. Time period is the time taken for one complete cycle or oscillation. Mathematically, frequency (f) is given by the formula:
f = 1/T
Where f is the frequency and T is the time period.
Calculating the Number of Changes in One Second:
In this question, the frequency is given as 50Hz. Using the formula mentioned earlier, we can calculate the time period as follows:
f = 1/T
50 = 1/T
Solving for T, we find:
T = 1/50 = 0.02 seconds
This means that in one second, there are 1/0.02 = 50 cycles or oscillations.
Since the direction of the potential changes once in each cycle, the direction of the potential changes 50 times in one second.
Therefore, the correct answer is option 'B' - the direction of potential changes 100 times in one second.
