So far we've only seen circuits that allow a single path for electricity to flow–but it doesn't HAVE to! Here's a picture of what we call a parallel circuit. See how there's one power source and two electrical devices?Conductor wires connect the battery to each bulb independently.

Since the electricity can either go into the first bulb and light it up, or on to the next bulb and light that one . . . it does both! Some electricity flows to each bulb, distributing the power equally to both. So parallel circuits have more than one path for electricity to follow!
