Volts

Voltage

Amperes

Current

Ohms

Resistance

Ohms Law

V = \frac{I}{R}

Impedance

= Resistance for Nerds

Current

How many electrons flow through a circuit in a second

Polarity

Means if a component is symmetric or not Polarised means that a component is not symmetric

Voltage Divider

LED

Anode - The shorter Leg Cathode - The longer Leg

Diode

Anode

The positive end of a diode

Cathode

The negative end of a diode

Conventional Current Flow

When electricity was discovered people thought the electrons flow from the positive terminal to the negative, in actuality they flow in the opposite direction, but it is still possible to calculate the flow with the old way.
