Raw and boiled egg are made to spin on a smooth table by applying the same torque . The egg that spin faster is Raw egg Boiled egg Both will have same spin rate Difficult to predict
1. using Kirchhoff law find the current in following branch answer AB:(5/8) A, CA: (5/2) A, DEB: (15/8) A AD: (15/8) A, CD: 0 A, BC: (5/2) A 2. using Kirchhoff law find the current in following branch Answer current in branch AB= (4/17) A In branch BC = (6/17) A In branch CD = (4/17) A In branch AD= (6/17) A In branch BD = (-2/17) A Total Current =(4/17) +(6/17)+(-4/17)+(6/17)+(-2/17)=(10/17) A 4. find R Equivalent
