## Series: The Characteristics of Electricity

### 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

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

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

This video distinguishes the difference between conductors and insulators, and their importance.

### Differences Between Conductors and Insulators

This video explains the differences between conductors and insulators.

### Electroscope

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

### Methods of Charging an Object

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

### 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

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

### Resistance

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

### 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.
