It's too much!!! what's wrong here?
V = 24 VDC, R = 12 Ohm.So,I = 2 A, P = 48 W.An almost 50 W resistor... ¿¿¿??? It's too much!!!
R = 12 OhmAn almost 50 W resistor... ¿¿¿??? It's too much!!
Yeah but 12 Ohms is little more than a dead short....
QuoteYeah but 12 Ohms is little more than a dead short....Yep and could look like a glowing heater if you used the right wire, or put it in a bulb and make some light.

AlbuinoAll other responders have basically stated that the dissipated power is indeed 48watts.However, what you need to ask yourself is "Why do I not trust or believe calculations derived from very basic equations that I claim to understand" This is not intended as a criticism but rather a suggestion that you need to enhance your experience in the application of theory before you replace it by intuition.
This might be redundant for many, but I want to point out that Power is also proportionate to the square of the Voltage.
