SUMMARY
An electric current can exhibit both alternating and continuous characteristics in scenarios such as ripple on the DC output from a poorly smoothed power supply and the DC supply to the LNB on a satellite TV dish. The mathematical representation of this phenomenon can be expressed as $$ I(t) = I_0 \sin (\omega t) + I_1 $$. Additionally, in a Buck topology DC-DC converter, the current through the inductor shows a triangular waveform with an average output current that is regulated by the converter's output voltage. This behavior is influenced by the switching frequency and the inductance value.
