Electrical Engineering The best multi-junction solar cells have an efficiency of about 40% for converting light energy from the sun into electricity. Estimate the size of a photocell that would be required to supply all the annual energy used by the US. (The average energy density from sun striking the surface of the earth is ~ 1.0 kW/m2 and assume that the cell is illuminated for 8 hours per day) The US consumes 100 quadrillion btu of energy.

Two metallic terminals protrude from a device. The terminal on the left is the positive reference for a voltage called Vx (the other terminal is the negative reference). The terminal on the right is the positive reference for a voltage called Vy (the other terminal being the negative reference). If it takes 1 mJ of energy to push a single electron into the left terminal, Determine the voltages Vx and Vy.
