Purpose
• Plugs and cords are distracting, but necessary. Today everyone is connected to an electronic device. All of these devices need plugged in, and usually by all different types of plugs.
• Wireless electricity technology exists. Using a WiTricity demonstration kit, can I design a device to transmit and receive a measurable amount of electricity?
