Fisika 2011 (menghitung hambatan total)


ujian praktikum fisika 2010/2011
Judul     :   Menghitung Hambatan Pada Resistor
Tujuan   : Siswa diharapkan dapat menentukan dan menghitung besarnya hambatan dalam sebuah resistor berdasar cincin warna suatu resistor.
                 Siswa diharapkan dapat menghitung besarnya hambatan total resistor dalam rangkaian

Alat dan Bahan
1.      1.  Multimeter (AVO-meter)
2.      2.  Rangkaian Resistor

Cara Kerja
  1. Hitung besarnya hambatan dalam tisp resistor dengan melihat warna cincin dari masing – masing resistor !.
  2. Catat hasil penghitungan pada tabel !
  3. Catat hasil pengukuran pada tabel di bawah ini ;
