Answer
The best method to treat a burn is D, running cold water over the burnt area until the pain reduces. This approach helps to cool the skin and reduce inflammation.

Answer
The power in an inductor is best described by option C, reactive power. Inductors store energy in a magnetic field, and this energy oscillates between the source and the inductor.

Answer
In a parallel RLC circuit, it becomes more capacitive when option A, Xc > Xl. This condition indicates that the capacitive reactance exceeds the inductive reactance.

Answer
If the resistance in a parallel resonant circuit increases, the total current will C, increase. This is due to higher voltage drop across the elements.

Answer
In systems with large inductive loads, they typically have D, low power factor with current lagging the voltage because inductive loads draw more reactive power.
