Homework Statement


Hi,

I have this question regarding to the smoothing effect of full wave rectification. In order to smooth out the wave. A capacitor is added across a resistor which is connect across a diode bridge. In order to increase the smoothing effect 2nd capacitor can be added across the resistor. So it means that are two parallel capacitor connected across the resistor. My question is instead of adding the 2nd capacitor to the resistor. How if i increase the resistance of the resistor (connected parallel with the 1st capacitor only)? would this also increase the smoothing effect as similar as two capacitor in parallel connected across a resistor?

Any one can help me? I can't find the answer to this question!

As you describe it the resistor is acting as the load on the rectifier setup. When the rectifier input voltage drops below the current voltage held on the capacitor, where is the load drawing its current from? What happens to the voltage on the capacitor? What if you change the amount of current being drawn by the load (by changing the load resistance)?
 

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
