3 pieces of Polaroid sheet (light intensity)
Homework Statement Unpolarized light of intensity I0 passes through two pieces of Polaroid sheet. The second piece is rotated so that the intensity of the transmitted light goes to zero. A third piece of Polaroid is inserted between the two pieces. Calculate the intensity as a function of...- togahockey15

Designing a DC transmission line
Homework Statement Design a dc transmission line that can transmit 225 MW of electricity 185 km with only a 2.0% loss. The wires are to be made of aluminum and the voltage is 660 kV. 2. Homework Equations P= IV = I^2 * R R= p(L/A) Power loss = Pf - Pi Attempt at a solution I worked through...- togahockey15
