Basic Components
Resistors
Capacitors
Inductors
Diodes
1.Resistors
Values
specified in ohms (Ω), kiloM arked with value using a color
code-ohs (K), or mega-ohms (M)
2.Capacitors
Values
specified in microfarads (μF) or picofarads (pF)
Marked with actual value or a numeric code
Some varieties are +/- polarized
3.Inductors
Values
specified in henries (H), millihenries (mH) and microhenries (μH)
A coil of wire that may be wound on a core of air or other
non-magnetic material, or on a magnetic core such as iron powder or ferrite.
Two coils magnetically coupled form a transformer.
May be classified by
semiconductor material
silicon,
germanium, gallium arsenide, etc.
Or classified by circuit function
