Study Notes
Electricity: Series and Parallel Circuits
- Series Circuit: Current flows through all components in a single path. If one component fails, the entire circuit stops functioning. Components are connected end-to-end.
- Parallel Circuit: Current flows through multiple paths. Failure of one component does not affect the rest of the circuit. Components are connected across each other.
Circuit Differences
- Voltage (Series): Total voltage is the sum of individual voltage drops across each component.
- Voltage (Parallel): Voltage is the same across each component and equals the voltage source.
- Current (Series): Current is the same throughout the entire circuit.
- Current (Parallel): Total current is the sum of the individual branch currents.
- Resistance (Series): Total resistance is the sum of individual resistances.
- Resistance (Parallel): Reciprocal of total resistance is the sum of reciprocals of individual resistances; total resistance is less than the smallest individual resistance.
Calculating Circuit Components
- Voltage Drop: Decrease in voltage across a component due to resistance.
- Ohm's Law: Voltage (V) equals current (I) times resistance (R). (V = IR)
- Total Resistance (Series): RT = R₁ + R₂ + R₃...
- Total Resistance (Parallel): 1/RT = 1/R₁ + 1/R₂ + 1/R₃...
Circuit Types: Symbols and Labels used
- Direct Current (DC): Current flows in one direction.
- Alternating Current (AC): Current changes direction periodically.
- Voltage: Symbol (V), Unit (Volts)
- Resistance: Symbol (R), Unit (Ohms)
- Current: Symbol (I), Unit (Amps)
Additional Notes
- Circuit Failure: In a series circuit, if one component fails, the entire circuit stops working. In a parallel circuit, failure of one component doesn't affect others.
- Multimeter Usage: Used to measure voltage drops.
