Is the step response nature the reason why a capacitor does not
the current through a capacitor is proportional to the rate of change of voltage across it. Thus: I = C * dv/dt KEY IDEA: a step change voltage waveform is not DC. Let that sink in. For DC, the time rate of change dv/dt = 0 for all time, from the Big Bang, to now, and until the heath death of the universe going forward. Zip. Zero. Nada.

Why capacitor pass AC and block DC current? [duplicate]
Consider a circuit with a capacitor, a voltage source, and a switch. Suppose the voltage source is DC and we flip the switch. If the capacitor is initially uncharged, then at the instant you close the switch current will flow as if the capacitor was not there.
Why does capacitor block DC and allow AC?
Hint: In this question, we need to explain the reason behind the capacitor blocks DC (direct current) and allowing AC (alternating current). We can say that the DC is a fixed value, which means that its polarity (direction) and magnitude do not alter with frequency, whereas AC''s polarity and magnitude do.

A capacitor blocks DC but it allows AC. Why? and How?
Therefore the electrons flowing in one direction (i.e. DC) cannot pass through the capacitor. But the electrons from AC source seem to flow through C. Let us see what really happens! DC cannot flow through a capacitor: Consider a parallel plate capacitor whose plates are uncharged (same amount of positive and negative charges).

6 FAQs about [The reason why capacitors block DC]
Why are DC-blocking capacitors important?
DC-blocking capacitors are indispensable in modern electronics, ensuring clean signal transmission by filtering out unwanted DC voltage. Their ability to block DC while allowing AC signals to pass makes them crucial in a wide variety of systems, from RF communication networks to audio amplifiers and power converters.
Why does a capacitor block DC and allow AC?
Hint: In this question, we need to explain the reason behind the capacitor blocks DC (direct current) and allowing AC (alternating current). We can say that the DC is a fixed value, which means that its polarity (direction) and magnitude do not alter with frequency, whereas AC's polarity and magnitude do.
Why do you need a blocking capacitor?
By preventing the DC voltage from passing, the capacitor ensures that the desired AC signal is preserved. This is especially critical in RF applications where signal clarity is paramount. For example, in a coaxial line, blocking capacitors can be used as inner or outer DC blocks to ensure the clean transmission of RF signals.
Why does a capacitor block DC in a steady state?
A capacitor blocks DC in a steady state only. When a capacitor gets charged fully and the voltage across it becomes equal and opposite to the DC input voltage, no more current can flow through it. This is when we say the capacitor is blocking DC. Whereas in the case of input AC supply, the voltage drops, becomes zero and reverses.
Why are capacitors used in DC circuits?
Capacitors are used in DC circuits for a variety of reasons. Their ability to block DC while allowing AC to pass makes them ideal for use in bypass, filtering, coupling, and decoupling applications. The transient nature of capacitors also allows them to be used in delay and timing circuits.
What is a DC blocking capacitor?
This is especially critical in RF applications where signal clarity is paramount. For example, in a coaxial line, blocking capacitors can be used as inner or outer DC blocks to ensure the clean transmission of RF signals. The behavior of a DC-blocking capacitor can be analyzed using the principles of an RC high-pass filter.
