Split-phase electric power - University of Utah Physics
... This is a three-phase 240 V delta connected system, in which one winding of the transformer has a center tap which is connected to ground and used as the system neutral. This allows a single service to supply 120 V for lighting, 240 V single-phase for heating appliances, and 240 V three-phase for mo ...

Tilt Switch App Circuits
... Using R1 of 4.7M and R2 of 1M, the current consumption will be about 0.5 uA (0.0005 mA) for a Vcc of 3.0 V. Higher values for R1 and R2 can be used to further limit the current, but board impedances must be considered if higher resistance is used. Experiment with C1 values for various filterin ...
