Final answer:
The power dissipated in a resistor can be written as P = I²R, where P is the power, I is the current, and R is the resistance.
Step-by-step explanation:
The power dissipated in a resistor can be written as P = I²R. This equation shows that the power dissipated is proportional to the square of the current flowing through the resistor and the resistance of the resistor.
