Forum:Equip spells and chaging the control of the monster equipped with them

1*For example, if I controll a monster equipped with some equp spell card and my opponent takes controll of that monster is that monster still equipped with that spell card? 2*And if that equp spell card is Mage Power, while that monster is equipped with it, it had 1000 more atk and def,but when the control of that monster is switched does the equipped monster gain atk and def for my opponents spell and traps on his side of the field or it keeps atk and def for all of my spells oand traps???
