An AC source is rated at . The time taken for voltage to change from its peak value to zero is ____.
Step 1: Given data
The time taken for the complete cycle is , which is the time period of the cycle. The time taken by half cycle will be . And the time taken to reach to the peak value from zero will be as it is equal to one-fourth of the complete cycle.
Step 2: Formula Used
, where is the time period, is the time taken to reach zero from the peak and is the frequency.
Step 3: Calculate the time to change from peak value to 0.
Calculate the time period using the formula
Calculate the time to reach 0 from the peak by using the formula
Hence, the time taken for voltage to change from its peak value to zero is .
