Question

what are sign convention of Kirchoff's second rule?​

Answer 1

Answer:

Kirchhoff's second rule requires emf − Ir − IR1 − IR2 = 0. Rearranged, this is emf = Ir + IR1 + IR2 = 0, which means the emf equals the sum of the IR (voltage) drops in the loop.

Answer 2

Answer:

Kirchhoff's second rule requires emf − Ir − IR1 − IR2 = 0. Rearranged, this is emf = Ir + IR1 + IR2 = 0, which means the emf equals the sum of the IR (voltage) drops in the loop.
