2. Features of an Electric Circuit Contains resistor(s) ex: fan, motor, bulb, bell Contains voltage source ex: battery, generator, outlet (power plant), solar cells (Sun) Contains wires making a closed path (= circuit) May contain switch turn circuit on and off

3. Circuit Symbols

4. Series Circuit = one path Either all lights on or all lights off (ex: flashlight, small bathroom) 1→ 2 or more bulbs, bulbs dimmer in series circuit as compared to parallel circuit

5. Parallel Circuit = two or more paths Each light bulb can be turned on or off independently (ex: classroom, kitchen/living room) 1 → 2 or more bulbs, bulbs brighter in parallel circuit as compared to a series circuit

6. Series and Parallel Circuit

7. Compare Series to Parallel Circuit
