  1. Pertemuan Ke-3 By: Ato Triyono,M.Pd NIDN. 0222117801 STIMIK DHARMA WACANA METRO Fisika ElektronikaAnalisis Rangkaian SUPERPOSISI

  2. Rangkaian Paralel • Tentukan : • R paralel (RP)...? • I Total • VR1 • VR2 • IR1 • IR2

  3. Penyelesaian • RP = R1 X R2/(R1+R2) • RP = 10 K ohm X 5 K ohm /(10 K ohm + 5 K Ohm) • =3,33 K ohm • Itotal = 12 Volt / 3,33 K Ω • I Total = 0,0036 Ampere • I Total = 3,6mA

  4. Ingat .... Ingat... • Pada Rangkaian parelel, Tegangan pada tiap-tiap titik adalah sama dengan Tegangan Sumber (Vs), Sehingga.... VR1 = VR2 = V sumber Jadi.... VR1 = 12 Volt, VR2 = 12 Volt

  5. IR1 = VR1/R1 • 12 Volt / 10 K ohm • = 0.0012 Ampere = 1,2mA • IR2 = VR2 /R2 • 12 Volt / 5 K ohm • = 0.0024 Ampere= 2,4mA I Total = IR1 + IR2 0.0036 = 0.0012+0.0024

  6. Rangkaian Paralel(3 Hambatan) • Tentukan : • RP • I Total • VR1 • VR2 • VR3 • IR1 • IR2 • IR3

  7. Mencari R Paralel • Rp-1 = R2 // R3 (R2 paralel R3) R2 X R3/(R2+R3) 5 KΩ X 5 KΩ/ (5KΩ+5KΩ) 25 KΩ / 10 KΩ = 2,5 KΩ Rp-1 = 2,5 KΩ R3 R1 R2 R1

  8. Mencari R Paralel • RP = R1// Rp-1 • (R1 paralel Rp-1) • 10 KΩ X 2,5 KΩ /(10KΩ+2,5KΩ) • = 2KΩ R1

  9. Atau.... RP dicari dengan Rumus

  10. I Total = Vs/RP = 12 Volt / 2 K Ω = 0.006 Ampere = 6mA VR1 = VR2 = VR3 = V sumber Jadi...... VR1 = 12 Volt VR2 = 12 Volt VR3 = 12 Volt VR2 VR3 VR1

  11. Arus Bagian Masing-Masing R IR1 = VR1 /R1 IR1 = 12 Volt / 10 K Ω = 0.0012 A = 1,2 mA IR2 = VR2 /R 2 IR2 = 12 Volt/5 KΩ = 0.0024 Ampere = 2,4mA IR3 = VR3 / R3 = 12 Volt / 5 KΩ = 0.0012 A = 2,4 mA IR2 IR3 I total = IR1 + IR2 + IR3 IR1

  12. Rangkaian Campuran (Seri dan Paralel) • Tentukan • R Total • I Total • VR1 • VAB • IR1 • IR2 • IR3 A B

  13. RP-1 = R2//R3 = 10 KΩ // 10 KΩ = 5 K Ω A B

  14. R Total = R p-1 + R1 • R Total = 5 KΩ + 5 KΩ • R Total = 10 K Ω I Total = Vs/ R Total I Total = 12 Volt/ 10 K Ω = 0.0012 A = 1,2mA

  15. VR1 = I Total X R1 • VR1 = 0.0012 X 5 KΩ • VR1 = 6 Volt VAB = Vs – VR1 • Atau VAB = I Total X Rp-1 • 12 Volt – 6 Volt = 6 Volt atau • 0.0012A X 5 KΩ = 6 Volt A B

  16. Rangkaian Campuran (Seri dan Paralel) , • Karena R2 dan R3 terhubung secara Paralel, Maka Tegangan VAB, mewakili tegangan pada VR2 dan VR3, yang besarnya sama yaitu 6 Volt A B

  17. Rangkaian Campuran (Seri dan Paralel) , • IR2 = VAB / R2 • IR2 = 6 Volt / 10 kΩ • 0.0006A = 0.6mA • IR3 = VAB/R3 • 6 Volt / 10 K Ω • 0.0006A = 0,6mA A B IR1 = IR2 + IR3 Sesuai dengan Kirchoff 1, arus masuk ke percabangan = keluar percabangan
