Challenge Problems

Push your limits with challenges.

Question 1

An AC generator produces a signal with a peak voltage of 240V and a frequency of 60Hz. Calculate the RMS voltage and the period of the wave.

πŸ’‘ Hint: Use the formulas for RMS and period.

Question 2

If the RMS current in an AC circuit is measured to be 5A, what is its peak value? Also, calculate the power consumed if the resistance is 8Ξ©.

πŸ’‘ Hint: First find the peak using RMS, then apply the power formulas.
