I don't know much about electrical engineering. I'm working on a project and need a 2.2k ohm resistor, but don't have one. However, I have 1.0k ohm and 1.2k ohm resistors. Can I combine one of each of these in a series as seen at the top of this page in place of the 2.2k ohm resistor? Could this cause any potential problems? Thank you!
