I am trying to make a load using resistor that can bear 12V 4A rated values. I have calculated a resistance but that has a low resistance and high power rated resistor i.e. 3 ohms 48 Watt resistor. It is impossible to find this so please help me regarding the load resistance. Thankyou
A resistor network will distribute the power dissipation across multiple resistors. Using three 10ohm 25W resistors in parallel will result in a 3.3ohm 75W resistance.

There are plenty to choose from such as this from Farnell: -
