A solar power panel produces current directly from sunlight. Since energy is conserved, if 1.4 kW/m2 of sunlight power falls on perfectly oriented panels with an area of 2 m2, what current will they produce when perfectly illuminated if it is designed to generate 48 V

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
