Alternating Current Study Guide for Chapter 32 Oscillations Alternating current involves current that oscillates over time. We usually the following formula for oscillations: max max one period C >    max cos  Here is the , and is the of the oscillation. Angular frequency has max amplitude angular frequency units of radians per second. frequency The is the number of oscillations (or periods) per unit time. It is related to the angular frequency by the formula    Frequency has units of number per second, or ( Hz sec). Hertz   Sometimes oscillations occur , meaning that the first period does not quite start at . out of phase    The formula for out-of-phase oscillations is max max phase shift C >      max cos  where is the . phase shift
