Direction: Q.36 to Q.40

Kirchhoff s circuit laws are two equalities that deal with the current and potential difference in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff.

Kirchhoff’s Current Law

This law states that, for any node in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node.

Kirchhoff’s Voltage Law

The directed sum of the potential differences (voltages) around any closed loop is zero.

Read the above passage carefully and give the answer of the following questions:

Kirchhoff s current law is conservation of:            

A) charge

B) energy 

C) potential                       

D) momentum
