please help, ive spent too long trying to figure this out, its killing me...anyone know how to do this?
A solar cell generates a potential difference of 0.345 V when a 700ohm resistor is connected across it, and a potential difference of 0.373 V when a 840ohm resistor is substituted. What are (a) the internal resistance (ohm) and (b) the emf (in volts, V) of the solar cell?
HELP!!!!! please!
thanks
BTW:
I have the correct answers but i have to show how to do it, the right answers are:
a.) 600 ohms
b.) .64 V
