AC Voltage-<strong>Current</strong> Conventions Assign a reference direction for current that leaves source at positive reference polarity When current has a positive value Its actual direction is same as current reference arrow 7 AC Voltage-<strong>Current</strong> Conventions When current is negative Its actual direction is opposite that of current reference arrow 8 4
Frequency Number of cycles per second of a waveform Frequency Denoted by f Unit of frequency is hertz (Hz) 1 Hz = 1 cycle per second 9 Period Period of a waveform Time it takes to complete one cycle Time is measured in seconds The period is the reciprocal of frequency T = 1/f 10 5
