A pulsating direct current is a direct current (dc) that changes in value at regular or irregular intervals.
A pulsating direct current may change in value, i.e., be always present but at different levels, or it may be a current that is interrupted completely at irregular or regular intervals (at specific frequency), but when present, is always in the same direction.
Pulsating currents are commonly created by using diode rectifiers or by DC sources connected in series with AC sources (where the amplitude of AC ≤ DC).
Famous quotes containing the words direct and/or current:
“Lesbian existence comprises both the breaking of a taboo and the rejection of a compulsory way of life. It is also a direct or indirect attack on the male right of access to women.”
—Adrienne Rich (b. 1929)
“Without the Empire we should be tossed like a cork in the cross current of world politics. It is at once our sword and our shield.”
