Consider a 6 cm2 dye sensitised solar cell with reverse saturation current Jr=10-10A/cm2. When the solar irradiance is 1,000 W/m2, it produces an equivalent photo current/short circuit current of 15 mA/cm2 at 300 K. Find out the open circuit voltage (V) of the cell?Assume a p-n junction ideality factor 1.5 and neglect any series and parallel resistance
You are working with a design team on a new product and are assigned to design the power supply. The requirements for the power supply are as follows: Input AC: 115 V AC +- 10%, 50-60 Hz Outputs: +5 V DC at 100 ma, +-12 V DC
In animation programs, special effects are achieved by changing the properties of objects. What instruction is used to change the opacity and color properties of objects in the Zeus example world?
Generate a new random variable X with pdf fX. Specifically, we want to generate a Gaussian random variable and relationship between Rayleigh and Gaussian distributions.
Determine the Polar form of the Impedance for the three components when they are Connected in series circuit and when they are connected in a parallel circuit. Determine it the final impedance is inductive or capacitive. Given: VPP = 400V, IRMS = ..
A museum has three rooms, each with a motion sensor (m0, m1, m2) that outputs 1 when motion is detected. At night, the only person in the museum is one security guard who walks from room to room.
Consider a 500-gallon tank that needs to be filled when the level goes below 25 gallons and will stop when the level goes above 475 gallonsControl systems can be either open-loop or closed-loop
