Variable impedance means, for example, at least a diode or a breakdown diode is connected in each cell for providing a low impedance when the write gate pulse is applied to the photovoltaic ferroelectric element and for providing a high impedance when the photovoltage produced by the photovoltaic...
1) Participants will build and use an electrochemical cell.2) Participants will use knowledge about the hand crank generators and photovoltaic cellsto construct, test, and draw conclusions about series and parallel circuits.3) Participants will apply what they know about series and parallel circuits ...
