CHEMMASTER6000 and Bakhtawar your gettin confused with Markovnikov's rule
...clearly not a chem master after all lol

K1 states that at any junction in a circuit, the current entering is equal to the current entering
its based on the conservation of charge - it says that current is conserved, so if current is conserved then charge must be conserved (as current = rate of flow of charge)

K2 states that around any loop in a circuit, the sum of the emf's = sum of pd's
its based on the conservation of energy - emf and pd are both forms of work done per unit charge, so if charge is conserved then energy must also be conserved

lol @ chemmaster's response
@dan.kl :nycly explained thanx !

dan.kl:
no problem :) its all good revision for my physics exam on wednesday haha
hope i helped

electrical charge is conserved....and it states that sum of current approaching a junction=sum of current leaving the junction.....see the diagram....I1+I2=I3+I4

kirchoff's 2nd law....also known as the loop rule
it states that total emf of the circuit=total potential difference across all the resistors in the circuit

--- End quote ---
absolutely correct. i wanna add that loop law is based upon conservation of energy

Thanks all for helpin me .. bt my problem is solving the questions from the past pprs like the one m/j09 q 7 ..
