A sine wave
A curve having a form of a wave or a sine wave is also what we called a sinusoid. It is also termed as a repetitive oscillation. A phasor is represented by a sinusoidal function as a complex number. It's phase difference is about less than or equal to 90 degrees. It is usually get the angle on where the voltage leads the current. Such simple indications are given in order to remember the following: the mnemonic "ELI and ICE man." It is remembered as "ELI" when the voltage leads the current by 90 degrees, with an emf(E),which is ahead of the current(I) and an inductor(L). Otherwise, "ICE" will be remembered when the voltage lags the current.
