1. A solar cell generates a potential difference of0.0806 V when a 500 Ω resistor is connected acrossit, and a potential difference of 0.1241 V when a 1000Ω resistor is substituted. What is the internal resistance of the solar cell?

2. What is the emf of the solarcell?

3. The area of the cell is 5.0cm2, and the rate per unit area at which it receives energy from light is 2.0m W/cm2. What is the efficiency of the cell for converting the light energy to thermal energy in the 1000 Ωexternal resistor? (percent = Do not enter a unit)
