how calculate value?

hai iam new commer . i have a problam please help me? how calculate the values of resisters and capaciters.
 

how calculate value?

Hi,
This is simple:
12:5=(R1+R2):R2
This give you 7K & 5K Ohm, But with C_you must tell what you need to make/have?
Pls remeber; 12K on 12V delivers for you no practicable current-only voltage-potential!
How much energie/current do you need or with what kind of time constant?
K.

hai iam using this for pic sensing voltage to read adc .i want to read 12v battery adc(full charge condition & low level)
 

Re: how calculate value?

If you want to read the voltage from a 12V battery, you probably need a full scale ADC reading that represents more than 12V (a fully charged lead battery can go to more than 14V).
