Bitesize ohm's law
WebThis law, also called Kirchhoff's second law, or Kirchhoff's loop rule, states the following: The directed sum of the potential differences (voltages) around any closed loop is zero. Similarly to Kirchhoff's current law, the … WebMay 29, 2024 · Ohm law is a relationship between three physical phenomena: current, voltage, and resistance. Current is defined as the flow of positive charge from a source to a negative charge source. The units for current are C/s for the amount of charge (C) that travels per unit time (s).
