3 cards from this section. Quick, good the night before a test.
What is the RMS value of a peak current of 5A?
Use the formula I<sub>rms</sub> = I<sub>0</sub> / √2.
What is the average value of an AC signal with a peak voltage of 100V?
Remember the formula for average voltage.
What does RMS stand for?
Think about the mathematical process used to determine effective values.
The RMS current is equal to:
Remember the formula for RMS current.
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?
Use the RMS and average formulas and consider the power as P = V<sub>rms</sub> I<sub>rms</sub>.
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.
Use the charge formula Q = I * t for total charge and E = P * t for energy.
