What is the frequency of pulsating DC output voltage?
If the rectifier circuit is supplied power from a 60-hertz ac line voltage, 60 pulses of load current will occur each second. Therefore, The RIPPLE Frequency of a Half-WAVE RECTIFIER Is The SAME AS The LINE Frequency….

What do you mean by pulsating current?
Definition of pulsating current : a direct current that has recurring more or less regular variations in magnitude.
Is pulsating DC same as AC?
Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC.
How do you measure pulse voltage?
Pulse voltage measurement techniques include crest voltmeters, voltage dividers, capacitive probes, electro-optical transducers, and reflection attenuators. Spark gaps can be used for the measurement of crest values of voltage pulses from 1 kV to 2.5 MV.
What is high voltage pulse?
Recent Advances: HVPC is a monophasic pulsed electric current that consists of double-peaked impulses (5–200 μs), at very high peak-current amplitude (2–2.5 A), and high voltage (up to 500 V), at a frequency of 1–125 pulses per second.
How do you calculate pulse width?
Create a ratio that places the length of the cycle activity in the numerator and the length of the overall cycle in the denominator. Divide the numbers. Multiply the result by 100 percent. This yields the pulse width of the duty cycle.
What is a pulsed DC?
Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular (“flat-topped”), rather than sinusoidal, pulses.
What is DC current and AC current?
DC current is direct current, which means electricity only flows in one direction; AC current is alternating current, which means it flows in both directions. Batteries run on DC current, while AC current is what comes in through an electrical plug in the wall.
What is a DC voltage?
DC voltages are voltages where the charges travel in only one direction. Any voltage pattern that has a non – zero net area under the voltage – time curve can be identified as a DC voltage. DC voltages are produced in devices such as solar panels, thermocouples and batteries.
What is the symbol for DC voltage?
Similarly unit of DC (same in AC) voltage is volt and it is expressed as V. Here, some dc voltage symbols are mentioned below: Schematic symbol for DC voltage. DC voltage single battery or cell – +. DC voltage symbol for multiple battery – + – +. Dc voltage source symbol – + – +. Voltmeter (instrument) symbol.
