4. 21.8 Kirchhoff’s Rules for Complex DC circuits Used in analyzing relatively more complex DC circuits, e.g., when multiple circuit loops exist 1.Junction rule 2.

School Tie-up | Consider loop bchgeb. 0000078873 00000 n Similarly, the resistance between A and D is given by 6 × 6 / 6 + 6 = 3 W. Now, resistor AC is in parallel with the series combination of AD and DC. Signing up with Facebook allows you to connect with friends and classmates already Therefore, since AC and CB are in series, their combined resistance = 3 + 3 = 6 W. Resistance between A and B is given by, 1 / R = 1/6 + 1/3 = 3/6 or RAB = 2W. Alt txt: simple circuit . 0000052254 00000 n Solve for total current (I=V/R). 3. Alt txt : Potential-difference-between-points, l = E1 – E2 / r2 + r1 = 12 – 6 / 3 + 2 = 1.2 A, Hence, vC – vD = vA – vB = vM – vN = 8.4 V, i.e. combining resistors in parallel eliminates one loop from the circuit the combination of components can reduce the complexity of a circuit and render it suitable for analysis using the basic tools developed so far. 0000004526 00000 n Now solve (i), (ii), & (iv) simultaneously, you shall arrive at.
