Series: The Characteristics of Electricity
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).
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.
This video identifies and describes the functions of each component in a simple DC circuit such as the battery, switch, load, fuse and wire.
This video distinguishes the difference between conductors and insulators, and their importance.
This video explains the differences between conductors and insulators.
This video demonstrates how an electroscope can detect and measure the charge of a body.
This video explains how charges can redistribute themselves through friction, conduction, induction and polarisation.
This video demonstrates how the electric current that passes through a conductor is directly proportional to the potential difference across its ends.
This video defines potential difference and explains how it is measured.
This video explains how the dimensions, nature of material and temperature of a conductor affect its resistance.
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.
