The Electricity and Magnetism Group uses cutting-edge quantum physics measurement technology to establish national standards for the base units of electricity in voltage (V), resistance (Ω), and current (A) as well as derived units such as power (W) and energy (Wh). The group develops and disseminates measurement standards and technology for these fields through its research. Based on the developed measurement standard technology, the team provides calibration, testing, and performance evaluation services for key national industries such as the electronics and electric power industries, and the team also develops and disseminates core measurement standards technology for emerging industries such as semiconductors and display technology as well as the defense industry.
