Unit 5: Electricity & Magnetism

Question 1

Electric Charge

Answer 1

An inherent physical property of certain subatomic particles that is responsible for electrical and magnetic phenomena

Question 2

Electrical Potential Difference

Answer 2

The change in potential energy per unit of electric charge moved between two points

Question 3

Electric Current

Answer 3

The transfer of electrical energy along a conducting wire

Question 4

Electrical Resistance

Answer 4

A property of matter that describes how different it is for electric current to travel through a metal/conductor

Question 5

Kirchhoff’s Current Law

Answer 5

In a closed circuit, the amount of current entering a junction is equal to the amount of current exiting a junction

Question 6

Kirchhoff’s Voltage Law

Answer 6

In any complete path in an electric circuit, the total electric potential increase at source is equal to the total electric potential decreases throughout the rest of the circuit

Question 7

Ohm’s Law

Answer 7

The potential difference between any two points in a conductor varies directly with the current between two points if the temperature remains constant

Question 8

Electromagnetic Induction

Answer 8

The production of electric current in a conductor within a changing magnetic field

Question 9

Law of Electromagnetic Induction

Answer 9

Any changing magnetic field near a conductor induces a voltage in the conductor, causing an induced electric current in the conductor
