Circle correct statements for Energy Harvesting (EH) Is the process in which energy is captured from a variety of ambient energy sources and converted into usable electric power. EH can provide a large amount of power in tens to hunhreds of watts. EH current market in 2017 is more than double the market in 2012. Battery energy trend is about the same as CPU speed of microprocessor trend. Primary batteries have reached commodity status with billions/yr shipped. Energy Harvesters can not be designed as cost effectively as Primary Batteries at this time. Typical voltages produced by both light and vibrational energy are in DC voltages. Why EH-powered systems must have energy storage? Give examples. Because energy source is not always available (solar at night, motor vibration at rest, air-flow, etc.) Circle (EH) electrical equivalent circuits for thermal couple transducer. An individual photovoltaic cell produces 0.5V@3A when connected to an external load, such as a light. The light is rated 10V/30W. How many photovoltaic cells is needed and how to connect them?

Correct Answer:
a)Is the process in which energy is captured from a variety of ambient energy sources and converted into usable electric power
b)EH can provide a large amount of power in tens to hundreds of watts
c)EH current market in 2017 is more than double the market in 2012
and d) Battery energy trend is about the same as CPU speed of microprocessor trend is wrong answer
