Study Notes
Circuits
Series Circuits
- A series circuit is a single-loop circuit where the current flows through each component in sequence.
- The current is the same throughout the circuit.
- The voltage drop is proportional to the resistance of each component.
- If one component fails, the entire circuit is broken.
Parallel Circuits
- A parallel circuit is a circuit where each component has the same voltage across it.
- The total current drawn from the power source is the sum of the currents through each component.
- If one component fails, the other components remain operational.
- Parallel circuits are commonly used in household electrical systems.
Electrons
- Electrons are negatively charged particles that flow through a conductor (e.g., copper wire).
- Electrons flow from the negative terminal of a power source, through the circuit, and back to the positive terminal.
- The flow of electrons is known as electric current.
Loads
- A load is a component that uses electrical energy to perform work (e.g., light bulb, motor).
- Loads can be resistive (e.g., light bulb), inductive (e.g., motor), or capacitive (e.g., capacitor).
- Loads are typically connected in series or parallel to a power source.
Current Flow
- Electric current is the flow of electrons through a conductor.
- Current is measured in amperes (A) and is affected by resistance and voltage.
- Current flow is from negative to positive terminal.
Short Circuit
- A short circuit occurs when there is an unintended flow of current between two conductors.
- Short circuits can cause overheating, fires, or electrical shock.
- Fuses or circuit breakers are used to prevent short circuits.
Volts
- Volts (V) are the unit of electromotive force (EMF) that drives electric current.
- Voltage is the potential difference between two points in a circuit.
- Voltage is affected by the resistance of the circuit and the current flow.
