Powering a pic

[CA Zuke]

Hi,

Can someone PLEASE tell me what the current (Amperes) should be for
powering a pic?

I use a L7805 voltage regulator but it still seems like I can get a
whole range of different levels of current depending on the batteries
use. (also you get different Amps for the L7805. Some are 0.1A and
others are 1A or even 2A)

I have 4 1.2V 1800mA batteries but I guess that current is far too
high. The 9V rechargable I have is 150mAh. How is it possible that the
9V has so little curent compared to he 1.2V??? I aways thought 9V is
stronger?

Anyway.. I really want to power my pic off a battery. So please let me
know what the current and voltage should be.

Thanks in advance

You'll first have to learn something about electricity. Voltage, current,
resistance and Ohms law. Otherwise you'll never be able to understand what
you need, let alone find out how to make it. I can't write a course on it
right now and any usefull answer on your question prerequites some basic
knowledge.
