It doesnt matter what resistance isconnected to the supply untill a load is connected. Mean if you measure the voltage after connecting 56K or 100K to 9volts, the out put will be 9 volts. Cheersaj_silverthunder said:
how can it be 9V,for example in this circuit,there u can see a 10k pot and the its output connected to 56K,the 10k varies the voltage to the varicap in order to change the capacitance,my doubt is how can i know the voltage supplied to BB139 when i change the 10K pot,thats my actual doubt!pranam77 said:
u said when the pot is turned around slowly, voltage to the wiper changes from 0V to 9V,but how can i know how much volt is passing through the pot!Audioguru said:

I think you mean to say..."so then measuring the volts passing to the varicaps can be measured by voltmeter" Yes...but the meter should have a high impedeance input or it will affect the readings. Mean as you connect the meter, the frequency will drift....Cheersaj_silverthunder said:
