Understanding Diode Output Waveform Reversal

AI Thread Summary
The discussion focuses on understanding the output voltage waveform of a diode circuit connected to an AC voltage source defined by V_{o}cos(ωt). Participants agree that the output should resemble a sine wave with a 10V amplitude, but there is uncertainty regarding the period of the waveform. Questions arise about how the output voltage would change if the positions of the resistor and diode were switched. One participant expresses confusion about the reasoning behind the waveform shape and requests a step-by-step explanation. The conversation highlights the need for clarity on diode behavior in AC circuits.

Sketch the output voltage as a function of time. The AC voltage source is V_{o}cos(\omega)t with V_{o} = 10V and \omega = 2000rad/sec.

I have posted a diode circuit question in the attachment

Ok, I think it should be a sine curve with a 10 V amplitude but am not too sure about the period.

What would the output voltage look like if the position of the resistor and diode were switched?

Can someone help me with this please.

What have you learned about diodes? What are they good for?



As for the period, T , you must know that \omega =\frac{2\pi}{T}

I have done clamping, clipping, half wave rectifier and full wave rectifier circuits. For the diagram, I think it is a cos wave with amplitude 10 V but have no idea why. I am genuinely lost here.

Can you explain to me step by step how I would go about reasoning as to what it should look like?
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
