The correct answer is: D. All above
The rules and laws of DC circuits also apply to AC circuits containing capacitance, inductance, and resistance. This is because the basic laws of electricity, such as Ohm’s law, Kirchhoff’s laws, and the power equation, are all independent of the frequency of the current.
However, there are some important differences between DC and AC circuits. For example, in a DC circuit, the current flows in one direction, while in an AC circuit, the current alternates between positive and negative values. This means that the impedance of an AC circuit is different from the impedance of a DC circuit.
In addition, the presence of capacitance and inductance in an AC circuit can cause the current and voltage to be out of phase with each other. This is known as reactive power, and it can cause problems in some applications.
Overall, the rules and laws of DC circuits also apply to AC circuits, but there are some important differences that need to be taken into account.
