When applying these formulas to AC circuits, remember to use complex numbers (impedance

Look for bridge patterns or T-networks before starting calculations. 4. Key Takeaways for Examinations For more practice problems and detailed solutions involving

Rleft=2+10=12 Ωcap R sub l e f t end-sub equals 2 plus 10 equals 12 space cap omega The star resistor R3cap R sub 3 is in a straight line with the bottom right resistor. Combine them:

When converting a star network to a delta network, you derive the outer loop resistances from the inner branch resistances. = Rx + Ry + Rx × Ry

Used when three resistors meet at a common neutral point. The equivalent delta resistance is the sum of the products of all pairs of star resistors divided by the star resistor opposite the delta branch. :

[ R_AB = R_A + R_B + \fracR_A R_BR_C = 4 + 6 + \frac4\times62 = 10 + \frac242 = 10 + 12 = 22\Omega ] [ R_BC = R_B + R_C + \fracR_B R_CR_A = 6 + 2 + \frac6\times24 = 8 + \frac124 = 8 + 3 = 11\Omega ] [ R_CA = R_C + R_A + \fracR_C R_AR_B = 2 + 4 + \frac2\times46 = 6 + \frac86 = 6 + 1.333 = 7.333\Omega ]
