This depends upon the rules of the state high school athletic association. For example, in Indiana a high school football player is limited to five quarters of participation per week. In Georgia, it's six quarters. In Montana, it's ten.
A player can play on either however they can only play the same total number of games the varsity plays. Example if the varsity team has a 20 game schedule the player can play no more than 20 games in total. So every JV game they play in will reduce the number of varsity games they can play in by 1.
