I think i have to find:
Power = current * voltage.
theoretically if you make a graph voltage-current and you put all your resistor measuring points on it then you draw a line trough those point. that line will cross the voltage and current axis.
if you take tose two values then you have...
Hi,
I am trying to do coursework on measuring the internal resistance of a solar cell. The light intensity on the solar cell is not going to change so the only thing that can be changed is the resistance as a variable resistor is used.But I am not sure how to find the internal resistance when I...
