Answer 19

A component or machine that spins when a current flows through it.

Question 20

What is a negative

Answer 20

The charge on an electron, or on an object that has had electrons transferred to it

Question 21

What is a neutral

Answer 21

Describes an object or particle that has no charge, or in which positive and negative charges cancel out, giving no charge overall.

Question 22

What is a neutron

Answer 22

A neutral particle found in atoms.
