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

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
