ELECTRONICS 1 CHAPTER 1

The electronics is the study of behaviour of ____________ in semiconductor

• Magnetic effect

• Electrons movement

• Temperature changes

• Chemical reaction

Which type of charge thus electrons have

• Negative charge

• Positive charge

• No charge

• undefined

Current is considered as the movement of

• nucles

• atoms

• protons

• electrons

If a fluid system is compared to an electrical system, the fluid pump will correspond to a

• conductor

• battery

• insulator

• lamp

If an electrical system is compared to a fluid system, the electrical current corresponds to the

•  water flow

• water wheel

• pump

• pressure

What is current?

• the repulsion of electrons

• the movement of electrons

• the abundance of electrons

• the presence of a positive charge

What is the unit and symbol for current?

• Ampere, Q

•  Ampere, I

• Coulomb, I

• Ampere, A

The rate of change of charge with respect to time is known as
