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...
