Understanding the V(in)=V(max).sin(wt) Formula for DC Smoothing Circuits

AI Thread Summary
The formula V(in) = V(max) * sin(wt) describes a time-varying voltage in a DC smoothing circuit, where V(in) represents the instantaneous voltage, V(max) is the peak voltage, and sin(wt) indicates the sinusoidal nature of the waveform. The angular frequency w, measured in radians per second, determines how quickly the waveform oscillates, with the cycle frequency f being related to w by the equation f = 2*pi*w. This formula is crucial for calculating the time at which the waveform reaches a specific minimum voltage, V(min). Understanding these components is essential for analyzing the behavior of DC smoothing circuits in power supply applications. The discussion highlights the importance of grasping the relationship between these variables for effective circuit design.

Can someone please explain to me in brief detail as to what each expression means for the given formula:-

V(in)=V(max).sin(wt)

and to how this formula works? It is a formula that has been given to me in order to work out time at which a waveform=V(min) for a dc smoothing circuit with a typical power supply.

V(in) is a voltage that changes with time. It changes with time in a sinusoidal fashion, with an amplitude of V(max). The angular frequency is w (units: radians/second) or a cycle frequency f=2*pi*w (units: cycles/second or Hz).
 
Thank you very much, I now understand.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
