On a plca of a flat capacitor of 5.92x10 ^ -13 faradios 1 microcurie (1 microcurie = 3.7x10 ^ 4 disintegrations per second) of a radioactive substance beta is deposited that for each disintegration emits an electron. Assuming that all the electrons emitted from one pole are picked up by the other plate, what is the voltage of the two plates after 1 second?

1) A quarantined physics student decides to make a parallel plate capacitor out of house-hold items. It turns out that the family dog finds the material the capacitor is made of quite yummy. The dog eats the capacitor plates (both top and bottom) at a constant rate of 0.1m/s. Assuming the voltage-difference between the plates is held constant at 10V and the distance between the plates is unchanged from its initial value of 10cm, what is the displacement current across...
