e.g Vcc is supply voltage to all collectors and Vee is common voltage for all emitters.
Since the introduction of ICs, Vcc and Gnd are used to designate positive and negative supply pins.

Dimensions
Dimensions in electronics are a mixed bag since the original standards were set in the imperial units and later on metric units have also been implemented, but some measurements were so widespread that they are still kept the same. For example, the distance between breadboard holes is 0.1″, which is same for a large number electronic components as well. In the metric system it becomes 2.54mm.
Common Calculations / Formulas
Resistor Value for LED
Vf = Forward Voltage
If = Forward Current
Vs = Supply Voltage
R = Required Resistance
R = (Vs – Vf)/If
Example:
Vf = 2.1V
If = 30mA = 30/1000A = 0.03A
Vs = 3.3V
R = (3.3 – 2.1) / 0.03 = 40Ω
