Hi I've started electronics in school recently but I found this confusing.
I understand that you would us a potential divider to get the desired voltage, but why would you want a different voltage?
For example in school we had a picture of a circuit with 9V going in to the divider, which split this into 6V, and the voltage went out into a 555 timer chip. Why is 6V better for a 555 timer chip than 9V? Also how would you know whats the optimum voltage for a certain component so you know which resisters to use in the potential divider?
Thanks a lot, I'm really new to Electronics and I'm taking exams soon so this info would be important.
