Study Notes
Series Circuits
- A series circuit is a circuit in which components are connected one after the other, forming a single loop.
- The current flows through each component in sequence.
- The total voltage of the circuit is the sum of the individual voltages across each component.
- The total resistance of the circuit is the sum of the individual resistances of each component.
- If one component fails or is disconnected, the entire circuit is broken.
Parallel Circuits
- A parallel circuit is a circuit in which components are connected between the same two points, forming multiple loops.
- The voltage across each component is the same.
- The total current drawn from the power source is the sum of the individual currents through each component.
- The total resistance of the circuit is less than the resistance of any individual component.
- If one component fails or is disconnected, the other components continue to operate.
Series-Parallel Circuits
- A series-parallel circuit is a combination of series and parallel circuits.
- Components are connected in series, and then these series circuits are connected in parallel.
- The total voltage and resistance of the circuit are calculated using the rules for series and parallel circuits.
- Series-parallel circuits can be used to create complex circuits that combine the advantages of both series and parallel circuits.
