Wireless electricity or witricity is useful where interconnecting wires are inconvenient or hazardous.
Efficiency is critical to good design and economical operation. Methods include:
- Direct induction, (most common, widely used for electric kettles and for charging electric toothbrushes)
- Resonant magnetic induction
- Electrical conduction via contact points
- Electromagnetic radiation in the form of microwaves or lasers
