Study Notes
Series Circuits
- In series circuits, there is only one path for current flow.
- Total resistance increases as more loads (e.g., light bulbs) are added.
- Voltage across each load decreases with addition of loads.
- If one load fails, the entire circuit is broken.
- Each load acts as a resistor, affecting the overall current.
Parallel Circuits
- Parallel circuits have multiple paths for current flow.
- The voltage across each load is the same as the source voltage.
- Total current through the circuit is the sum of currents through all branches.
- Loads operate independently. If one load fails, the others remain functional.
- Voltage is constant across each parallel branch, sum of currents equals total current coming out of source.
