Cable or Wire

1. Wire 2. Connected Wire

3. Non-Connected Wire

Definition:
Used to conduct electricity from one component to the next.

-When the dot is present the wires are electrically connected/common.

-When there is no dot the lines cross only for the sake of the drawing and aren't connected/common.

Antenna or Aerial

1. Radio Antenna 2. Radio Antenna alt

3. Dipole Antenna

Definition:

An Antenna is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna’s terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.

Capacitor (originally Condenser)

1. IEEE Capacitor 2. IEC Capacitor

3. Polarized IEEE Capacitor

4. Polarized IEC Capacitor

5. Variable Capacitor

Definition:

A Capacitor is a passive two-terminal electrical component used to store energy in an electric field. For comparison, an inductor stores energy in a magnetic field, and a resistor does not store energy but rather dissipates energy as heat.

Diode

1. Diode 2. Zener Diode

3. Schottky Diode

4. Vericap Diode or Varactor

5. Tunnel Diode

6. Light Emitting Diode or LED

7. Photodiode

Definition:

A Diode is a two-terminal component with an asymmetric transfer characteristic. Low Resistance (0) to current flow in one direction and high resistance (∞) the other direction.

Inductor

1. Inductor 2. Iron Core Inductor

3. Variable Inductor

Definition:

An Inductor (also choke, coil, or reactor) is a passive two-terminal electrical component that stores energy in its magnetic field. For comparison, a capacitor stores energy in an electric field, and a resistor does not store energy but rather dissipates energy as heat.
