Case Study: What’s the buzz on Smart Grids 1) How do smart grids differ from the current electricity infrastructure in the United States? The main difference where the smart grids differ from the current electricity infrastructure in the United Sates is that there is no information currently available as to how much energy/electricity is being used and where it is being used. In simple words it can be said that currently there is no exchange of information between the provider and the consumer

Lesson Plan: Electric Circuits (~130 minutes) Concepts 1. Electricity is the flow of electric charge (electrons). 2. Electric Charge is a property of subatomic particles. 3. Current is the movement of electric charge. 4. Voltage is the electric potential that exists to move a charge. 5. Power is the rate at which electric energy is flowing in a circuit. 6. Ohm’s Law: Power = Voltage x Current. 7. Resistance is a physical property that quantifies how well a charge

Chapter I I. Introduction Power electronics converters can be found wherever there is a need to change voltage‚ current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics‚ electrical currents‚ and voltage are used to carry information‚ where as with power electronics‚ they carry power electronics becomes the efficiency An inverter converts DC

form of electricity or cost effective‚ another idea or form of electricity was needed. Welcome Nikolas Tesla‚ he came up with the idea of AC (Alternating Current) with this form of electricity the flow of electric charge changes direction periodically in relation to a sine wave. With this new type of electricity it could be sent much further due to

electrons to form hydrogen gas. Because the zinc strip frees electrons and the copper strip uses electrons‚ if you put a wire between the two strips‚ then electrons will flow from the zinc to the copper. This is electrical energy. The flow of electricity is called an electrical current‚ which is measured in a unit called amperes (also called amps for short). Electrical current cannot just flow on its own; it needs something to "push" it. Voltage (also referred to as electric potential) is what pushes
