When you want to produce a variation of 5% in the current using a capacitor in paralel with a resistor of 1khom how do you do it?
What are the calculations ? and the result?
Thanks

At some frequency, you can put in a capacitor across the resistor that will have a reactance that reduces the resistance by 50 ohms.

The formula and such are in our Ebook - http://www.allaboutcircuits.com/vol_2/chpt_4/2.html
