Which of the following statements regarding circuits are true? O To find resistance in a parallel circuit, you must sum the individual resitances O The direction of conventional current is the direction of positive charge flow. O In a circuit, electrons flow from high potential energy (at the negative terminal) to low potential energy (at the positive terminal). O When electricity is passed through a lightbulb, the electrons are 'used up' by the bulb. O All voltages in a loop sum to 12V O The current that flows into a resistor is the same as the current that flows out. O To 'short circuit' something means there is an alternate path of less resistance for the current to flow. O Switching on a light happens immediately because electrons move from the power source to the bulb incredibly quickly. O A 'kilowatt-hour' is a unit of power, not energy.
