Japan Successfully Generated Electricity in Space and Transmitted It to Earth Japan has achieved a major milestone in space-based solar power by successfully generating electricity in space and transmitting it wirelessly to Earth. The experiments used microwave transmission to send energy collected by solar panels back to receiving stations on the ground. Unlike Earth-based solar systems, space solar arrays can generate power continuously without interference from weather or nighttime. While cur

In this Q&A video, we explain how to calculate Earth Fault Loop Impedance (Zs) for an electrical circuit step-by-step. Learn: ✅ What Earth Fault Loop Impedance is and why it matters. ✅ The components of the fault loop and how impedance affects circuit safety. ✅ How to apply BS7671 regulations and calculate Zs using Ze and (R1 R2). ✅ Real-world examples with a 50A Type B MCB and 10 mm² cable in a 9 kW boiler circuit. This video is part of our electrical design training series in collaboration wit

Total Earth Fault Loop Impedance Zs = Ze R1 R2 for TN-S and TN-C-S Earthing Arrangements How to calculate or measure total earth fault loop impedance for an installation connected to a TN-S and TN-C-S earthing arrangements. In this video I show drawings to aid with City and Guilds and EAL electrical exams at level 1, 2 and 3. The total earth fault loop impedance Zs of a circuit is made up for the impedance of the supply authorities cable Ze and the circuit impedance of the line conductor R1 and
