1. In a solar photovoltaic cell, the current generated is proportional to the intensity of the light. A photovoltaic cell is connected to a particular circuit monitoring station, the cell produces a current of 10 mA when the intensity of light is 200 mW / cm ². The current flows through the photovoltaic cell circuit (monitoring station), which has an internal resistance of 4 ohms. What is the voltage drop (in volts) through the control station, when the light intensity is 600 mW / cm ²? Response volts. 2. For illumination given, a photovoltaic solar cell open circuit produces an emf of 0.46 volts. The cell is connected through a "burden" with a resistance of 400 ohms. Suppose that the EMF across the solar cell is the same as the value of open circuit. What heating power is generated in the resistance, watt?

1. 10 mA to 200 W / cm ²: 30 mA to 600 W / cm ², as we are told that the current is proportional to the intensity. E = IR = (0.03 V) (4 Ω) = 0.12 V. 2. P = E ² / R = (0.46 V) ² / (400 Ω) = 5.3 × 10 ^ -4 W = 0.53 mW.
