Series: The Characteristics of Electricity


Ammeter, Voltmeter and Multimeter

Ammeter, Voltmeter and Multimeter

This video explains the uses of the ammeter and demonstrates how they must be connected in a circuit. It also describes how a multimeter can measure different electrical quantities (i.e. current and voltage).
Characteristics of Parallel and Series Circuits

Characteristics of Parallel and Series Circuits

This video describes the characteristics of a parallel circuit and explains how the different components are connected. It also looks at the characteristics of a series circuit.
Components of a Simple DC Circuit

Components of a Simple DC Circuit

This video identifies and describes the functions of each component in a simple DC circuit such as the battery, switch, load, fuse and wire.
Conductors and Insulators

Conductors and Insulators

This video distinguishes the difference between conductors and insulators, and their importance.
Differences Between Conductors and Insulators

Differences Between Conductors and Insulators

This video explains the differences between conductors and insulators.
Electroscope

Electroscope

This video demonstrates how an electroscope can detect and measure the charge of a body.
Methods of Charging an Object

Methods of Charging an Object

This video explains how charges can redistribute themselves through friction, conduction, induction and polarisation.
Ohm's Law

Ohm's Law

This video demonstrates how the electric current that passes through a conductor is directly proportional to the potential difference across its ends.
Potential Difference

Potential Difference

This video defines potential difference and explains how it is measured.
Resistance

Resistance

This video explains how the dimensions, nature of material and temperature of a conductor affect its resistance.
Static and Current Electricity

Static and Current Electricity

This video describes and explains the differences between static and current electricity. It also looks at static discharge, and how static charge builds up in a thundercloud.
