Final answer:
The true power in a 2 amp series RL circuit with a 100 ohm resistor is 400 watts.
Step-by-step explanation:
In a 2 amp series RL circuit with a 100 ohm resistor, the true power can be determined using the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance.
Substituting the given values, we have P = (2 A)^2 * 100 Ω = 4 A^2 * 100 Ω = 400 W.
Therefore, the true power in the given circuit is 400 watts.
