- 2. WHAT IS A CIRCUIT ? A circuit is a closed loop or a complete course of conductors through which current can travel. • Most basic circuit you can get is a power source and a load (something to use the current). Ex. Battery (power source), Light bulb (load), Wire (use to connect them) • Current flow is positive going (red colored wire)
- 3. SERIES CIRCUIT • A series circuit is a circuit where there is only one path from the source through all of the loads and back to the source. This means that all of the current in the circuit must flow through all of the loads.
- 4. SCHEMATIC DIAGRAM • A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. • A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.

- 7. PARALLEL CIRCUIT - A parallel circuit has two or more paths for current to flow through. - Voltage is the same across each branch/component of the parallel circuit. - The charge divides into multiple pathways, passing through only one of the branches. Any charge that passes through Bulb 1, will not pass through Bulb 2 or Bulb 3.

- 9. DIFFERENTIATE SERIES FROM PARALLEL CIRCUIT Series Circuit • the current through each of the components is the same. • the voltage across the circuit is the sum of the voltages across each component. • Current is constant Parallel Circuit • the total current is the sum of the currents through each component. • the voltage across each of the components is the same. • Voltage is constant
