the behavior of electric charges, including how charge is transferred between objects by friction, by contact, by induction Name the three ways that charge can be transferred law of conservation of charge whenever there is a charge transfer, the total charge is the same before and after the transfer occurs
Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
