What Formula is Needed to Find the Capacitor Value for a Half Wave Rectifier?

AI Thread Summary
To find the capacitor value for a half wave rectifier supplying a load current of 100 mA at 60 Hz with a ripple limit of 160 mVpp, the relevant formula is V_r = I_dc / (fC). In this equation, V_r represents the ripple voltage, I_dc is the direct current, f is the frequency, and C is the capacitance. Users are encouraged to search for "half-wave rectifier capacitor filter" for further clarification and understanding. This will ensure a comprehensive grasp of the concept and its application. Understanding this formula is essential for calculating the required capacitor value accurately.

Homework Statement



A half wave rectifier is supplying a load current of 100 mA. The input frequency is 60 Hz. Find the capacitor value required to limit the ripple ot 160 mVpp.

Really... I can solve this I'm sure... But I'm wondering what formula I need to use... I've never been shown one in class, and I don't have a textbook, so a little help with a formula would be nice...

its V = IR
 
somebody please?
 
I think the equation you're looking for is V_r=I_{dc}/fC.
Where Vr is the ripple voltage, Idc is the direct current, f is the frequency of the supply voltage, and C is the capacitance. But I would do a search for something like "half-wave rectifier capacitor filter" to learn about it and be sure that you agree with it. OK? I don't want to mislead you.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
