Abstract

PURPOSE:To measure load supply electric power without being affected by a frequency, temperature, etc., by connecting a magnetic field generating means to an electric power supply path and measuring a magnetic field generated by this magnetic field producing means by the magneto-resistance elements which is bridge-connected. CONSTITUTION:The magnetic field generating means 7 is connected between a power source 5 and a load 6 and generates the magnetic field proportional to the supplied electric power from said means 7. The bridge-connected magnet- resistance element group 8 is arranged nearby this magnetic field producing means 7 and at least one of the magneto-resistance elements is so arranged as to vary in magnetic resistance with the magnetic field generated by said means 7. When the electric power is supplied from the power supply source 5 to the load 6, the magnetic field generating means 7 generates the magnetic field to lose the balance of the bridge and a voltage is developed at an output terminal 9. For the purpose, this output voltage is measured to measure the supplied electric power.
