Circuit Analysis When a circuit has more than one element, a circuit analysis is required to determine circuit parameters ( v , i , power, etc.) in different parts of the circuit. Circuit Theories: Ohm’s Law Superposition Theorem Kirchhoff’s Voltage and Current Laws Mesh/Nodal Analysis Source Transformation Thevenin/Norton Theorem Wye/Delta Transformation
Mesh (Loop)  Analysis ~ I 1 I 2 I 3 Steps: - assume loop current I 1 for Loop 1, I 2 for Loop 2, etc. - apply KVL for each loop - obtain ‘n’ no. of equations for ‘n’ no. of loops - the loop currents are the unknown variables - solve equations to determine loop currents - obtain currents through each circuit elements - apply Ohm’s Law to calculate voltages - use Power equations to calculate P, Q
