Final answer:
To calculate the power dissipated by a resistor in a DC circuit, use Joule's law: P = I²R.
Step-by-step explanation:
The power dissipated by a resistor in a DC circuit can be calculated using Joule's law, which states that power (P) is equal to current (I) squared multiplied by resistance (R), P = I²R.
In this case, if the current through the resistor is 0.600 A and the resistance is 1.00 Ω, we can substitute these values into the formula to find the power dissipated by the resistor:
P = (0.600 A)²(1.00 Ω) = 0.360 W
