1. ### transformer core explanation required

hello everyone, this is a stupid question but if anyone can answer this, i'd be so grateful. the question is about the transformer core. take a simple EI laminated silicone steel core for example. we know primary winding magnetises and secondary demagnetises. and at a some point an equilibrium...
2. ### Inductance of distributed air gapped core

Hey, I have got two sets of E70/33/32 core of N87 material, one set with centered airgap of 8mm and another set is un-gapped core. I measured the inductance for N number of turns with centered gapped core and also I measured the inductance with 4mm airgap in the each leg (which gives effective...
3. ### Tapping inductors

Hello guys, I really need your help on this. I am designing an Inductor which is rated for 50A and 350 Vrms for 85Khz. I want to get 3 inductance value from one inductor so i decided to tap between the points or to use switch to get the required inductance. I just want to know if my...
4. ### Capacitance and Inductance of twisted pair cable

In one of the article of "All About Circuits" about capacitance and inductance of twisted pair cable i found a set of formulae for computing capacitance and inductance of twisted pair cable based on diameter , spacing and dielectric constant as seen in the snapshot.. Can anybody give me the...
5. ### finding the number of turns for my inductance.

Hey guys, so i've calculated that I need an inductance of 0.150mH for my inductor. However, I'm trying to figure out the number of turns I need for it. # I've got an answer of 24 turns but this doesn't feel right to me. Could someone double check my calculations? below is the datasheet for the...
