Web7 apr. 2024 · Ohmic losses represent the voltage drop across the circuit. According to the ohm law, the voltage drop across a circuit is directly proportional to the current flowing in the circuit. V ∝ I ⇒ V = I R Where, R is the constant known as resistance. The power of a circuit is the product of the voltage and the current across the circuit. Mathematically, WebAccurate Inductor Loss Determination Using Würth Elektronik’s REDEXPERT Fig 1: B-H Curve The second type of core loss is due to eddy currents, which are induced in the core material by a time-varying flux ∅ . According to Lenz’s Law, a changing flux induces a current that induces a flux in opposition to the initial flux.
