Oblicz opor zastepczych opornikow ktore pokazane sa na schemacie R1= 12 omow R2=R3=24 R4=R5=48

R1=12Ω R2=R3=24Ω R4=R5=48Ω Rz=? -------------------------------------------- Rz1=R2+R3=24Ω+24Ω=48Ω 1/Rz2=1/Rz1+1/R4 !/Rz2=1/48+1/48=2/48=1/24 Rz2=24Ω Rz=R1+Rz2+R5=12Ω+24Ω+48Ω=84Ω

R2 + R3 = 24 + 24 = 48 zatem 1/Rz1 = 1/( R2 + R3) + 1/R4 = 1/48 + 1/48 = 2/48 = 1/24 czyli Rz1 = 24/1 = 24 Rz = R1 + Rz1 + R5 = 12 + 24 + 48 = 84 Odp. Rz = 84 omy ====================
