  1. PERTEMUAN 2 PENGANTAR ELEKTRONIKA DASAR

  2. SATUAN INTERNASIONAL • Panjang (L) =meter • Massa (m)= Kg • Waktu(t) =sekon • ArusListrik(I) =ampere • Muatanlistrik(Q) =coloumb • Teganganlistrik (E,V,U)= volt • Dayalistrik (P)= watt • Energi/ usaha (W)= joule,KWH • Resistansi (R) =ohm • Induktansi ( L, XL)=henry • Gaya (F)= newton • Frekuensi (f)= Herzt • Intensitascahaya(J)=candela • Temperatur(T)= derajatcelvin • Resistifitas (ᵨ)=Ohm meter • Konduktifitas(K) siemens/meter • Konduktansi (G)= siemens (Mho)

  3. ELEKTRON DAN PROTON • Padadasarnyatiapbendaterdiridariduajenispartikelyaitu: proton danelektron • Proton mempunyaimasksa 1,66x10 -27 kg • Elektronmempunyaimassa 9,1x10 -31 kg • Sebuahelektronmempunyaimuatanlistrik sebesar1,602x10-19 Coloumb • Satucoloumb = 6,24x1018elktron
