Passive components are the devices which do not require any external source for the operation and are capable of storing energy in the form of voltage or current in the circuit. That wire is often but not necessarily formed around a core of iron or steel or some other magnetic material. 2. Common examples of passive components include: 1. Despite the fact that the dielectric in the capacitor does not pass any electrons, a current—which in this case is called a displacement current—effectively moves through the capacitor. Passive elements include resistances, capacitors, and coils (also called inductors). Another distinction is between linear and nonlinear: Linear elements – these are elements in which the constituent relation, the relation between voltage and current, is a linear function . Video type Thus, as resistance goes up, the current through the element comes down, so that at high resistances the current is very small. The amount of that opposition is called its resistance, which is measured in ohms (Ω). In most circuits, they are connected to active elements, typically semiconductor devices such as amplifiers and digital logic chips. The capacitor's opposition to alternating current is called its capacitive reactance, which, like resistance, is measured in ohms (Ω).
