10.1 Kirchoffs Law And Circuits

Question 1

State Kirchhoffs second law

Answer 1

The sum of the emf is equal to the sum of the p.d. around a closed loop

Question 2

Explain why Kirchhoff second law is a result of the conservation of energy

Answer 2

Second law is emf = p.d around a circuit
The total energy per unit charge transferred into electrical energy must equal the total energy transferred from electrical energy into their energy stores
