Total current or charge entering a junction is exactly equal to the charge leaving the node which means all the currents entering and leaving the junction should be equal to zero. Which circuit law is mentioned in this context?

Total current or charge entering a junction is exactly equal to the charge leaving the node which means all the currents entering and leaving the junction should be equal to zero. Which circuit law is mentioned in this context? Correct Answer Conservation of Charge

CONCEPT:

Law of conservation of charge:

  1. The total charge of an isolated system remains constant.
  2. The electric charges can neither be created nor destroyed, they can only be transferred from one body to another.
  3. Total current or charge entering a junction is exactly equal to the charge leaving the node which means all the currents entering and leaving the junction should be equal to zero.
  • The law of conservation of charge is obeyed both in large scale and microscopic processes.
  • In fact, charge conservation is a global phenomenon i.e., the total charge of the entire universe remains constant.

EXPLANATION:

  • From above it clear that charge can neither be created nor be destroyed, but it can be transferred from one object to another by using some methods like induction and conduction. Therefore option 1 is incorrect and options 2 and 4 is correct.
  • If the charges are distributed in a system, then the net charge of the system remains constant. Therefore option 3 is correct
