Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An AC circuit has a peak voltage of 360V and a peak current of 15A. Calculate the RMS voltage, RMS current, average voltage, and average current. If the system operates for 10 hours, what is the total energy consumed?

💡 Hint: Use the RMS and average formulas and consider the power as P = V<sub>rms</sub> I<sub>rms</sub>.

Challenge 2 Hard

A circuit experiences a peak current of 20A flowing for a minute. Calculate the total charge transferred and the energy consumed if the circuit runs at an average voltage of 240V.

💡 Hint: Use the charge formula Q = I * t for total charge and E = P * t for energy.
