Spell Bee Word: Resistor


What does resistor mean?

Word: Resistor

Part of Speech: Noun

Meaning: Resistor means a small part in an electric circuit that slows down or limits the flow of current.

Sounds like: resister (a person who fights against something)

How do you spell resistor?

Syllables: re - sis - tor

Tricky part: Resistor sounds exactly like resister, a person who resists, but the two words end differently, so check the ending when you mean the circuit part.

Watch out for: resistar, resistre, resistur

Memory tip: Match the vowel to the meaning: a resister is a person, with the e of person; a resistor is an object, with the o of object.

Resistor in a sentence

Example 1: We added a resistor to the circuit so the bulb would not burn out.

Example 2: The science teacher showed us a resistor no bigger than a grain of rice.

Example 3: A resistor in the toy car stops too much current reaching the little motor.

Fun Fact

Many resistors carry coloured bands that show how much they hold back the current. In this colour code, black stands for 0 and brown for 1.
