sudden urge to act
A sudden strong feeling that makes you want to do something without thinking first.

Частая ошибка:

Синонимы
urge (A general strong desire, not necessarily sudden or unplanned.)
|
whim (A sudden idea or wish, often lighter and less intense than 'impulse'.)

2
brief burst of energy or signal
A short, quick movement of electricity or signal in the body or a device.
Частая ошибка:
Some learners confuse 'impulse' with 'pulse'; 'pulse' can mean a regular beat, but 'impulse' is usually one short burst.
Синонимы
signal (A general term for transmitted information; may be longer-lasting than an impulse.)
|
pulse (Often refers to repeated signals, while 'impulse' is a single event.)
Антонимы
steady current (A continuous flow of energy, unlike a short burst.)
