I have a few questions for you guys.
1. What does the watt rating mean on a resistor?
2. If I (according to a calculator) need a 330 ohm, 1/4 watt resistor, is that the same as a 165 ohm (330/2), 1/2 watt resistor?
3. How do I know how what potentiometer I need? For instance, I'm going to use potentiometers to control an RGB LED strip (link). It's 2 amps for the whole strip at 12VDC. However, I'm planning to cut it down to 1/30 of its original size. What resistor do I get then and how do I calculate that?
Thanks,
