4 cards from this section. Quick, good the night before a test.
What does AC stand for?
Recall the term we discussed in the beginning.
What is the peak current in an AC circuit?
Think about the highest point of the wave.
What is the definition of alternating current?
Think about how the current flows: back and forth.
AC stands for?
It's a key term in electrical engineering.
Given an AC circuit with a peak voltage of 12 V and a frequency of 60 Hz, calculate the angular frequency.
Remember the relationship between frequency and angular frequency.
If a sine wave of current starts at a peak voltage of 5 V and a phase difference of π/4, write the expression describing this AC wave.
Pay attention to the phase value in the equation.
