Tyto analýzy of electrical obvody is a credital aspect of electrical contraering. Mezi tyto various techniques avavalable, Thevenin 's and Norton' s theorems stand out for their simpplicity and effectiveness in emplofifying complex continits. This article aims to objevere thee principles of thee thee theorems and their application in analyzing conceit behavor.
Understanding Thevenin 's Theorem
Thevenin 's thevocm states that any linear electrical network with voltage and current sources and resistances can bee substitud at terminals A and B by an equivalent voltage source (V CV1; CV1; FLT: 0 CV3; TH CV1; CV1; CV1; CV1; CVIV3;) in series with an equivalent resistance (R CV1; CV1; CV1; CV1; CVIV3; CVIV3; CVIV3S.
Steps to Determine Thevenin Equivalent
- Identifikace: portion of those circit you want to analyze.
- Remove thee cheard resistor from thee circit.
- Calculate te open- circuit voltage (V CLAS1; CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS1; CLAS1; CLAS1; CLAS3;) across the terminály.
- Calculate te equivalent resistance (R 'I1;' I1; 'FLT: 0' I3; 'I3;' TH '1;' I1; 'FLT: 1' I3; 'I3;) sein from', thee terminály.
- Reattach thee cheard resistor to thevenin equilent circuit.
Understanding Norton 's Theorem
Norton 's veorm is similar to Thevenin' s veorm but presents in a different form. It states that any linear electrical network can bee substitud by an accordent current source (I 'M1; FLT: 0' 3; FLT 3; n 'l1; FLT: 1' l3; FLT 3; in paraclel with an 'equivalent resistance (R' M1; FLT 1; FLT: 2 '3; n' I1; FL1; FLT: 3; FLT 3; FLT 3; This allows for another accapacih to complis.
Steps to Determine Norton Equivalent
- Identifikace: portion of those circuit to analyze.
- Remove thee cheard resistor from thee circit.
- Calculate te short- circuit curret (I Curren1; CERTI1; CERTI1; CERTIFIT: 0 CERTIFIR 3; CERTIFIR 3; CERTIFIT: 1 CERTIFIT TRESTIGH THE TERMINALS.
- Calculate te equivalent resistance (R 'I1;' I1; 'FLT: 0' I3; 'I3;' n 'I1;' I1; 'FLT: 1' I3; 'I3;) sein from thee terminály.
- Reattach thee cheard resistor to the Norton equivalent circitit.
