I've noticed that Ohm's law is used like everywhere!!! But it's hard for me to understand how to use it... for example:
if i have an LED which runs on 1.5 V but i don't have 1.5 V battery, i only have 12V battery, and if i attach that LED to 12V battery it would burn emediatly, so i want to know how strong the resistor must be to resist those 10.5 volts, and how to know how many Volts equals to 1 Ampere, or how many Amperes equals to 1 Volt.
I wish you could help me with this, because if i wont unerstand this i would be stuck int this level forever... Thank You
