Dc Circuits. A circuit is a closed loop through which electrons can flow. A direct current (DC) circuit is a type of circuit with direct current (as opposed to alternating current) flowing through it. That is, in a DC circuit, the current flows in one direction.
In terms of AC and DC Coupling, what is Coupling? Quite simply, coupling is the transfer of energy from one medium to another, for example, from a metallic wire to an optical cable. This transfer of energy may be desirable or undesirable. What is DC coupling? DC coupling allows both AC (alternating current) and DC (direct current) signals to pass through a connection. What is AC coupling? AC coupling allows only AC signals to pass through a connection. A DC source can be considered to be like a battery, in that there is a constant negative charge from the batteryâs negative terminal to the positive terminal. An example of such a source is shown in Figure 1.
