Parallel circuits are one of two fundamental circuit configurations we come across every day. Like a parallel universe, parallel circuits and networks can give us unexpected results. Adding more gives less, and voltage stays the same no matter what! Learn about the role resistance plays in parallel circuits for your designs and safety.

Qi (pronounced as "chee") charging is an optimized inductive charging concept also known as “wireless charging,” allowing you to charge your devices wirelessly. Compatible devices’ batteries are charged by using induction transfer without requiring separate chargers, cables or adapters... Simply place your compatible device on top of the wireless pad and watch your device charge. Finally--an end to cords!
