One of the effects a capacitor has in a DC circuit is that it will __________.

In a DC circuit, a capacitor will charge to a voltage equal to the source voltage over time. When a voltage is applied across a capacitor, it begins to store electrical energy in the form of an electric field. This charging process continues until the voltage across the capacitor matches the voltage of the power source.

Once fully charged, the capacitor acts as an open circuit for direct current (DC), meaning that no steady-state current flows through it. Thus, while it does not provide a continuous direct current itself, its ability to charge and establish a voltage is crucial in various applications, such as filtering, timing, and in power supply stabilization.

Considering the other options, a capacitor does not discharge immediately; instead, it takes time based on the circuit's resistance and the capacitor's capacitance. It also does not provide direct current, as its role is to store energy rather than act as a source of current. Additionally, a capacitor does not eliminate resistance in a circuit; resistance is a fundamental property of all circuit components, and a capacitor can actually interact with it in various ways (e.g., in RC circuits).
