Circuit analysis is a fundamentamental skill in electrical incorporaering. One powerful technique for simplifying complex indictes is Thevenin 's therem. This article explores howw to analyze indicrite behavior using Thevenin' s equilent indicriterit.

Teoretycy Thevenin 'a

Thevenin 's thereim states that any linear electrical network wigh voltage and current sources andd resistors can be replaced at terminals A and B by an equivalent voltage source (V precision 1; precision 1; FLT: 0 precision 3; Thevenin precidens 1; FLT: 1 precidens 3; FLT: 3 precificient resistance (R precification easier talyze; FLT: 2 preciden3; Thevenin precidens 1; expires: 3; FLT: 333; 3assupér analyze; FLT).

Problem badania

Let 's consider a simple obwody to demonstrować te kroki. Assume we have a obwody with a 12V battery, a 4mbH resistor, and a 6δ resistor in serie.

Step 1: Identify the Circuit

We will analyze the obwód between the terminals of the 6mbH resistor.

Step 2: Removie the Load Resistor

Removie the 6mbH resistor to find the open- oburits voltage.

Krok 3: Oblicz te Open- Circuit Voltage

Te voltage across thee 4mbH resistor can be calculated using thee voltage divider rule:

  • V Xi1; Xi1; FLT: 0 XI3; XI3; XI3; XI1; FLT: 1 XI3; XI3; = VI1; FLT: 2 XI3; XI3; TI3; XI1; FLT: 3 XI3; XI3; * (R XI1; XI1; FLT: 4 XI3; XI3; 4δ 1; XI1; FLT: 5 XI3; XI3; / (R XI1; XI1; FLT: 6 XI3; XI3; 4λ; XI1; FLT: 7 XI3; + R XI1; XIX1; FLT: 8 XIX3; XIX3; XIX3; 6λ 1; FLT: 9 XIXIX3;)))
  • V Xi1; Xi1; FLT: 0 Xi3; Xi3; 4δ XI1; Xi1; FLT: 1 Xi3; Xi3; = 12V * (4δ / (4δ + 6δ)) = 4,8V

Thus, V, V1, V1, V1, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V2, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V3, V@@

Step 4: Find the Equivalent Resistance

To find R present 1; Xi1; FLT: 0 presenta3; Xi3; Thevenin presenta1; Xi1; FLT: 1 presenta3; Xi3;, we turn off thee independent source (replacee the 12V battery with a short indict):

  • R XX1; XI1; FLT: 0 XX3; XI3; Thevenin XX1; XI1; FLT: 1 XX3; XI3; = R XX3; XI1; FLT: 2 XX3; XI3; 4ŘX1; XI1; FLT: 3 XX3; XI3; + R XI1; XI1; FLT: 4 XX3; XI3; 6δ 1; XI1; FLT: 5 XXX3; XI3; = 4δ + 6δ = 10∞
