We know the frequency of a direct current is zero. The reason is that there is no repetitive pattern. But I was stumbled when I noticed, why can't that straight line be cut into smaller pieces, and can we treat it as infinite frequency? I have included a picture below as an example.

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
11 paź 2014 · frequency is the amount of times a signal is repeated per second. for example a square signal goes like this: 1-0-1-0-1-0 in 1 second. Then the frequency is 3Hz. A DC signal is constant.
Direct current is a unidirectional flow of electric charge. The most important example of DC is an electrochemical cell. Direct current has the flexibility to flow through conductors, mainly wires. The frequency of DC is zero (0 Hz).
20 gru 2014 · Yes, you can have alternating current (AC) that alternates with a frequency less than 1 cycle per second (a period longer than 1 second). If you connect a battery and a resistor using a properly wired DPDT switch, you would be able to reverse the voltage across the resistor, at will.
17 kwi 2020 · DC current is defined as a unidirectional flow of electric charge. In DC current, the electrons move from an area of negative charge to an area of positive charge without changing direction. This is unlike alternating current (AC) circuits, where current can flow in both directions.
Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.
