A) Conservation of charge, conservation of momentum
B) Conservation of energy, conservation of charge
C) Conservation of momentum, conservation of charge
D) Conservation of charge, conservation of energy
Correct Answer: D
Solution :
Kirchhoff's Ist law or\[KCL\]states that the algebraic sum of current meeting at any junction is equal to zero. In other words, we can say that" the sum of all the currents directed towards a junction in a circuit is equal to the sum of all the currents directed away from that junction. Thus, no charge has been accumulated at any junction i.e., charge is conserved, and hence we can say that\[KCL(\Sigma i=0)\]is based on conservation of charge. Kirchhoff's IInd law or KVL states that algebraic sum of potential drops around any closed loop must be zero. In other words, "around any closed loop, voltage drops are equal to voltage rises". No energy is gained or lost in circulating a charge around a loop. Thus, we can say that KVL is based on conservation of energy.You need to login to perform this action.
