The Technical Committee for Electricity and Magnetism (TC-EM) further develops the discussion of technical issues related to electrical metrology. The technical areas are important to support industry and researchers. TC-EM focuses on:

• Realisation of the SI units of electromagnetism
• Determination of electromagnetic constants and fundamental tests
• Quantum electrical metrology
• DC voltage, resistance, and current
• AC resistance, capacitance, inductance
• AC voltage, current, power and energy; power quality
• High voltage and current
• Other DC and low frequency measurements, including electric charge, phase angle, current and voltage waveform
• Electric, magnetic, and electromagnetic fields
• Radio frequency and microwave measurements;THz metrology
• Electromagnetic properties of materials, including electrical conductivity, dielectric and magnetic properties
• Electrical and magnetic measurements at the nanoscale
