Apoint charge of magnitude q is at the center of a cube with sides of length l. a)what is the electric flux through each of the six faces of the cube? b)what would be the flux through a face of the cube if its sides were of length l1 ?

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
