Hi,I have a noob question,hehe
let's say I have a step down transformer rated at 12V,2A

does the load circuit will draw the amp that they need or will the power supply release 2A to the circuit?

thanks.

The transformer is max 2A it can give. So your circuit must below 2A. Draw more than that will spoil your transformer or fuse blow or voltage drop.

Added on December 10, 2011, 10:00 amIs there anywhere I can get a big farad capacitor cheap. Used 1 also no problem.

Some call it super capacitor or ultracapacitor.

Increase the speed.

Reduce the right hand side friction that support the rotor.

Or change the motor to lower rpm type.

Anybody know of affordable place to make these?

https://oshpark.com/shared_projects/ABh5pwX8

I googled for some places but most of them seem to require 10+ pcs min order which I don't really need so many.

Is there any place local that does, say, 5pcs min order?

You can try this.

If 10pcs is cheap, just make it. It is between the price and qty.
