20. Energy / Electricity Your Turn to do something Use the Multimeter to find the voltage and current of the solar panel This is called the open circuit voltage and current Rotate the panel to the sun and watch the voltage and current Now connect panels in series and parallel and test the voltage and current Using the wind turbine see what sort of voltage you can create
