parallel circuit
Học thuậtThân thiện
Definition
Noun: A type of electrical circuit where the components are connected across common points or junctions, providing multiple separate paths for the electric current to flow. The voltage across each component is the same, but the current can divide among the different branches.
Usage
A "parallel circuit" is a fundamental concept in electrical engineering and physics. It describes a specific wiring configuration. - It is used to describe the physical layout of electrical components like resistors, lamps, or outlets in a building. - It is contrasted with a "series circuit," where components are connected in a single path.
Examples
- Basic Usage:
- Most household lighting is wired in a parallel circuit so that if one bulb burns out, the others remain lit.
- To calculate the total resistance in a parallel circuit, you must use the reciprocal formula.
- Technical Context:
- The engineer designed the system using a parallel circuit to ensure consistent voltage to all sensors.
- In the lab, we built both a series and a parallel circuit to observe the differences in current and voltage.
Advanced Usage
- "To be wired in parallel": This is a common phrase describing how components are connected to form a parallel circuit.
- The batteries are wired in parallel to increase the total current capacity while keeping the voltage constant.
Variants and Related Words
- Parallel connection (n): The act or instance of connecting components in parallel. Often used interchangeably with "parallel circuit" in informal contexts.
- A parallel connection of resistors lowers the overall resistance.
- In parallel (adverbial phrase): Functioning or connected in the manner of a parallel circuit.
- The devices operate in parallel, drawing power independently from the same source.
Synonyms
- Shunt circuit (n): A less common technical synonym, emphasizing the current-division aspect.
- Multiple-path circuit (n): A descriptive synonym highlighting the defining characteristic.
Antonyms
- Series circuit (n): A circuit where components are connected end-to-end in a single path, so the same current flows through all components.
Noun
- a closed circuit in which the current divides into two or more paths before recombining to complete the circuit
