Answer:
B) approaches infinity
Explanation:
The capacitive reactance of an AC capacitor is given by;
Where;
C is the capacitance
f is the frequency of the ac voltage
Therefore, as the frequency of the ac voltage across a capacitor approaches zero, the capacitive reactance of that capacitor approaches infinity.
The correct option is (B) approaches infinity
The answer is A because potential energy is stored up energy which means that it’s not moving
When the current is time-dependent, the circuit has a
capacitor. A capacitor could be used to store energy. As you use it up, the
energy depletes. This is why it is time-dependent. The answer is 12 seconds. I
