Electricity

Question 1

Electric circuit

Answer 1

A path for electrons to follow, consisting of a power supply, one or more loads, and conductors joining the power supply and loads

Question 2

Electric Charge

Answer 2

The physical property of matter that causes it to experience a force when near other electrically charged matter. Electric charge can be positive or negative.

Question 3

Nucleus

Answer 3

The central part of an atom, made up of protons and neutrons

Question 4

Electrons

Answer 4

negatively charged, very light particles in an atom. Electrons move around the nucleus of the atom.

Question 5

Negative electric charge

Answer 5

The charge on an atom or object with more electrons than protons

Question 6

Protons

Answer 6

Positively charged particles found in the nucleus of an atom

Question 7

Positive electric charge

Answer 7

The charge on an atom or object with fewer electrons than protons

Question 8

Neutrons

Answer 8

Particles with no electrical charge that are found in the nucleus of an atom

Question 9

Positively charged

Answer 9

Having more protons than electrons (more positive charges than negative charges)

Question 10

Negatively charged

Answer 10

Having more electrons than protons (more negative charges than positive charges

Question 11

Neutral

Answer 11

Have the same number of protons and electrons

Question 12

Static electricity

Answer 12

A build-up of charge in one place

Question 13

Power supply

Answer 13

A device that can provide an electric current

Question 14

Load

Answer 14

A device that uses electrical energy and converts it into other forms of energy

Question 15

Conducting path

Answer 15

connected series of materials along which an electric current can flow

Question 16

Electric Current

Answer 16

A measure of the number of electrons flowing through a circuit every second. An increase in current means an increase in the rate of flow of electrons in the circuit.

Question 17

Filament

Answer 17

A coil of wire made from a metal that glows brightly when it gets hot. The filaments in light globes heat up when electricity flows through them.

Question 18

Switch

Answer 18

A device that open and closes the electric current flowing

Question 19

Resistance

Answer 19

A measure of the electrical energy required for an electric current to pass through an object. The energy is changed to heat.

Question 20

Ammeter

Answer 20

A device used to measure the amount of current in a circuit

Question 21

Parallex Error

Answer 21

Error caused by the reading scale

Question 22

Voltmeter

Answer 22

A device used to measure the voltage across a component in a circuit.

Question 23

Random Errors

Answer 23

An error that occurs due to estimation when reading scales, or when the quantity being measured changes randomly

Question 24

Systematic Errors

Answer 24

Errors that are consistently high or low due to the incorrect use or limitations of equipment

Question 25

Electric Currents

Answer 25

The flow of electric charges that electrons follow

Question 26

Voltage

Answer 26

What makes electric charges moves

Question 27

Serius Circuit

Answer 27

A circuit with the components joined one after the other in a single continuous loop

Question 28

Parallell Circuit

Answer 28

A circuit that has more than one flow of electricity. If one path has a break in it, the other path will still be able to function.

Question 29

Resistance

Answer 29

The slowing down and reduction of electrons flowing through a circuit
