17. When batteries are connected in parallel connection the total voltage stays the same but when they are connected in series connection the total voltage increases. 18. A 1.5 voltage battery can supply the needed energy of 3 (1.5 v) bulbs in a series circuit. 19. The more bulbs you add to a circuit, the more difficult it will be for the current to flow. 20. If you unscrew one of the light bulbs in a parallel circuit, the rest will stop lighting.
