Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the peak value of an AC waveform if it reaches a maximum of 50V?
π‘ Hint: The peak value is the maximum voltage reached.
Question 2
Easy
What is the RMS value if the peak value is 80V?
π‘ Hint: RMS is calculated by dividing the peak value by β2.

Challenge Problems
Push your limits with challenges.
Question 1
A generator produces an AC voltage with a peak value of 240V. Calculate the RMS value. Then, what is the average value for half a cycle?
π‘ Hint: Apply both formulas correctly to find the two values.
Question 2
If a sinusoidal wave has a peak current of 60A, how much power does it deliver to a 20Ξ© resistor, considering the effective current?
π‘ Hint: Find the effective current first, then use the power formula.
