The Ohmic loss during the open-circuit test id considered negligible because:
1
the Ohmic loss is proportional to the square of the applied voltage, which is high in the open-circuit test
2
the Ohmic loss is proportional to the square of the applied current, which is low in the open-circuit test
3
the Ohmic loss is proportional to the square of the applied current, which is high in the open-circuit test
4
the Ohmic loss is proportional to the square of the applied voltage, which is low in the open-circuit test
