Electrical Circuits quiz review

• Generators work by converting mechanical energy into electrical energy. They are used to produce electricity.(like the magnet simulation we do)
• Electricity flows from positive to negative
• Renewable energy resource(water)

  Hydropower or flowing water
• Renewable energy resources from light

  Solar
• Renewable resources from wind

  Windmill
• Renewable Resources from plants

  Biomass
• Renewable energy resources within the Earth's crust

  Geothermal energy
• what are the 4 types of nonrenewable energy resources?

  Coal, oil, natural gas, nuclear energy
• How do windmills work?(from step 1 to step 4)

  step 1: Blowing Winds. Step 2: Spinning Blade. Step 4: Sending Electricity
• How do solar panel works?

  Photovoltaic Effect
• What are Photovoltaic cells mae of?

  These cells are made of silicon and release electrons
• What type of connection does Solar use? Ac or Dc

  Alternating Current
• how does a solar panel work?

  1. photovoltaic effect 2. generating electricity 3. inverter conversion 4. utility connection
• Solar Panel: When light hits the PV cells, it releases some atoms of electrons in the material(which is made of silicon).
• WHat type of form does Solar Panel has?

  Direct Current
• Electric current is a flow of electrons through a circuit
• Current(I) is measured by how many electrons pass a point during each second
• Voltage(V) is the amount of potential energy in the elctrons.
• A battery is a chemical reactions that cause a flow of electrons.
• Generator uses of moving magnets to create a flow of electrons.
• A load of Resistance is a device that uses electrical energy by converting it to heat, light, or mechanical energy.
• Wires provide a path for electrons to flow, there must be a complete circuit.
• Parallel circuits- the electrons flow in more than one path, and each resistor has its own loop.
• Series circuits- the electron flow only in one path.
• Combination circuits- some resistors are in series, some are parallel.
• Voltage is an electrical pressure, The higher the voltage, the more electrons flow.
• Amps are the number of electrons flowing through the wire.
• What is the combination of voltage and amps called?

  Watts
• Electricity is an atom
• How many volts can an eel generate?

  800 watts
• How does a hydroelectric dam create energy?

  water flow from top to bottom
• Why must all outlets/prongs have two prongs?

  electricity needs to flow in a complete loop. Electricity goes in one prong and goes out to the other prong.
• Resistance(R) is the opposition to the flow of charge in a circuit.
• Power is how quickly the energy is delivered or used
• What is a tesla coil trio?

  Three tesla coils connected together to create a synchronized and visually appealing electrical display.
• Geosphere: consists of the interior and surface of the earth, both of which are made of rocks.
• Biosphere: the limited part of the planet that can support living things comprises the second system.
• Hydrosphere: area of the earth that are covered with enormous amount of water.
• Atmosphere: an envelop of gas that keeps the planet warm and provides oxygen for breathing and carbon dioxide for photosynthesis.
• Cryosphere: contains huge quantities of ice at the poles elsewhere.
