Physics Unit 2 - Electricity and magnetism

Question 1

Static electricity

Answer 1

Static electricity is an imbalance of electric charges within or on the surface of a material.

Question 2

Current electricity

Answer 2

Current electricity is the flow of electrical charge or flow of charge carriers.

Question 3

Electric charge

Answer 3

Electric charge is a basic property of matter. Charge can be positive (like the charge on a proton) or negative (like the charge on an electron).

Question 4

Charged carriers

Answer 4

Charge carriers are charged particles that move through a conductor or through an electrolyte.

Question 5

Negative charge

Answer 5

The type of electrical charge electrons have.
Objects with more electrons than protons have a negative charge

Question 6

Positive charge

Answer 6

The type of electrical charge protons have.
Objects with less electrons than protons have a positive charge

Question 7

Conductor

Answer 7

A conductor is a material through which electric current is able to pass.

Question 8

Insulator

Answer 8

An insulator is a material that contains no charge carriers

Question 9

Ammeter

Answer 9

An ammeter is an instrument used to measure the current flowing through a section of the electric circuit.

Question 10

Voltage

Answer 10

Voltage is the potential difference between two points of a component in an electric circuit.

Question 11

Volt

Answer 11

The volt (V) is the unit of voltage.

Question 12

Voltmeter

Answer 12

voltmeter is an instrument used to measure voltage
