# circuit

«circuit» in Mova's school dictionary: **a complete loop of wires and parts that electricity flows…** — its meaning for a pupil, its sense in the lessons and examples, with 5 sentences of Mova's corpora that use it.

### part of speech

noun (a circuit, circuits)

### meaning for a pupil

1) An electrical circuit is a complete loop of wires and parts that electricity flows round, from the power source and back again. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#m1)

2) A circuit is a route or track that goes round in a loop, like a racing circuit. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#m2)

3) A circuit is one trip round such a loop. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#m3)

4) Circuit training is exercise where you go round a set of different activities. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#m4)

### sense in the lessons

In science, a simple circuit has a battery (cell), wires and a bulb, buzzer or motor; the circuit must be complete (closed) for electricity to flow; a switch opens or closes it. A series circuit has one path; a parallel circuit has more than one. Symbols are used in circuit diagrams. In PE, circuits are rounds of exercises. Phrases: «complete circuit», «open/closed circuit», «short circuit», «circuit diagram», «series circuit», «parallel circuit».

### examples

- The bulb lights up only when the circuit is complete. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x1)
- Draw a circuit diagram with a cell, a switch and a bulb. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x2)
- If you open the switch, the circuit is broken. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x3)
- We ran three circuits of the field. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x4)
- The racing cars sped round the circuit. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x5)
- In PE we did circuit training. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x6)
- A short circuit can start a fire. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x7)
- Never make circuits with mains electricity; only use batteries. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/circuit/#x8)

### note

Plural circuits. The «ui» sounds like «i»: «SUR-kit». In science, a gap anywhere stops the whole series circuit. Mains electricity from the wall is dangerous; school circuits use low-voltage batteries.

### In the corpora

- [Electricity is a flow of tiny charged particles through a path called a circuit.](https://md.mova.elamur.ai/free/en/corpora/school/everyday/32-electricity-at-home/0/)

- [A switch is a gate in the circuit.](https://md.mova.elamur.ai/free/en/corpora/school/world/55-electricity/4/)
- [Electricity flows only around a complete circuit.](https://md.mova.elamur.ai/free/en/corpora/school/world/55-electricity/10/)
