Electric Circuits
this question is related to a photovoltaic lab exercise we did. I'm not sure how to go about answering this question because we did not cover theory for this topic so I'm a little stuck.
Q: Assume your battery is connected directly to a battery system without a voltage regulator. Use your I-V curve to determine the current, voltage and power the module produces for the following battery voltages: 1) 6 V, 2) 12 V, 3) 24 V.
Any help will be really appreciated. Thanks!
