Kirchhoff law problem and equivalent resistance

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

class 10 video  what ohm's law? Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as, objective question based on electric current open this link for objective    https://nexttopperinstitute.blogspot.com/2020/07/class-10th-objective-questions-on.html   Class 10       HOW TO ORGANISM REPRODUCE Question. 1(i) What is fertilisation? Distinguish between external fertilisation and internal fertilisation. (ii) What is the site of fertilisation in human beings? Answer. (i) Fertilisation is defined as the fusion of a male gamete (sperm) with a female gamete (an ovum or egg) to form a zygote during sexual reproduction.
