Study Notes
Electricity: Circuits
-
Definition of a Circuit
- A closed path through which electric current flows.
- Composed of various components such as resistors, capacitors, inductors, and power sources.
-
Types of Circuits
-
Series Circuits
- Components connected end-to-end.
- Same current flows through all components.
- Total resistance is the sum of individual resistances.
- If one component fails, the entire circuit is interrupted.
-
Parallel Circuits
- Components connected across the same voltage source.
- Different paths for current to flow.
- Total resistance is less than the smallest individual resistance.
- If one component fails, the others can still function.
-
-
Basic Components of Circuits
-
Resistor
- Limits current flow and drops voltage.
- Measured in ohms (Ω).
-
Capacitor
- Stores and releases electrical energy.
- Measured in farads (F).
-
Inductor
- Stores energy in a magnetic field when current flows through it.
- Measured in henrys (H).

Definition of a Circuit
- A circuit is a closed path allowing electric current to flow.
- Composed of components like resistors, capacitors, inductors, and power sources.
Types of Circuits
Series Circuits
- Components are connected end-to-end, forming a single path for current.
- The same current flows through all components.
- Total resistance equals the sum of individual resistances.
- Failure of one component interrupts the entire circuit.
Parallel Circuits
- Components connect across the same voltage source, creating multiple paths for current.
- Total resistance is lower than the lowest individual resistance.
- If one component fails, the remaining components can continue functioning.
Basic Components of Circuits
- Resistor: Limits current flow and reduces voltage, measured in ohms (Ω).
- Capacitor: Stores and releases electrical energy, measured in farads (F).
- Inductor: Stores energy in a magnetic field when current flows, measured in henrys (H).
- Power Source: Supplies energy to the circuit (examples include batteries and generators).
