yeah with 470nf cap. i tried to run my voltmeter but its not working....i dont know whats happen. and how can i check whole components....individually or i need to check circuit is really run or not. please reply back
thanks for your advance recommends.

'Datasheet' is the manufacturer's information relating to the device/circuit/component.

without this capacitor can i run this voltmeter?

I doubt it.

Today i got 470nf cap , but its showed me its 474J. what does mean it ? shopkeeper told me its same like 470nf

 

[remon7]

anyway its 474J and 100volt <<<<<<<i am worried about it ...is it good . about 100volts

 

[alec_t]

474 means 470000 pF, i.e 470 nF, which is what you want. 100V rating is greater than the voltage your circuit uses so is fine.

i want 470nf cap...

I don't know whats going wrong in my breadboard???? it does not work well like schematic diagram.. just one dot is turn on...others OFF....

 

[alec_t]

Pictures of your breadboard don't help us. There must be a wrong or missing connection somewhere, or a dead component. Breadboards of poor quality give unreliable connections.

please check this video. i would like to know about this schematic diagram about this circuit board. because i have planned to submitting my previous project tooo. actually i got 1.5 volts from water turbine..

 

[remon7]

please give me this circuit diagram and components name and values..... Thanks
alec_t ...

 

[alec_t]

Sorry, I don't have the circuit diagram. The video showed nothing useful.
Google 'DC DC boost converter schematic'. There are loads of circuits out there.

What voltage is your battery
