Sir i think u dint actually get my point. There are 2 types of inductors. 1. That u make urself by using a wire of a certain lenght n thickness and making ciols of it. 2. That u can get if u know the inductance of an inductor like 10uH, 0.1uH, etc. It looks just like a resistor. It does not have any coils. The function of both is the same. I tried both while i was making FM transmitter. But only 2nd one worked. So, I just wanted to know if it is necessary to use a handmade inductor or we can use the one that looks like a resistor ( I dont know what to call it ) Thanks
