Abstract: A power measurement apparatus configured to measure power consumed at a load, the apparatus includes a magnetic film module, an adjuster, a measurement resistance, and a voltage detector. The magnetic film module is arranged so that a longitudinal direction of the magnetic film module is parallel to current flowing in the load. The adjuster is configured to adjust a pass-frequency and a phase of a voltage at one terminal of the magnetic film module. The measurement resistance is serial-connected to the magnetic film module. The voltage detector is configured to detect a voltage between both terminals of the magnetic film module.
