Circuit Schematic Drawings How many paths do electrons have to choose from as they travel? Which symbol is the electrical energy source (energy cell)? An electrical load uses electron energy. How many electrical loads are there? Which one is the motor? Which one is a light bulb? Which one is a resistor? What different devices do electrons flow through in this electron path (Circuit)? Is there a switch in this circuit? What are 2 the places in this circuit that a switch could be placed in order to turn every load on and off at once? What are two places that a switch could be placed so that just the motor and the resistor branch of the circuit could be turned on and off, leaving the light always on? How could wires be added to make electrons flow through these bulbs, one after another in series? How could wires be added to make electrons flow through these bulbs, on separate parallel branches? How could wires be added to make electrons flow through these bulbs, one after another in series? Which are series and which are parallel circuits? • Series circuit: when electron go through electrical loads, one after another. • Parallel circuit: when the electron path splits up and then rejoins again before going back to the power source.
