What is the difference between a capacitor and a resistor?

The main difference between a capacitor and a resistor is that a capacitor stores electrical energy while a resistor dissipates it. A capacitor has two terminals, one positive (called the “+” terminal) and one negative (called the “-” terminal). When a voltage is applied across the terminals, an electric field is created, which causes electrons to move from one terminal to the other. This movement of electrons creates an electrical current. In contrast, a resistor has only one terminal; when a voltage is applied across this single terminal, the resistance causes the current to decrease in value.
