This podcast (audio) file explains how electric current can be obtained from the sun through the solar panel using direct illumination of the sun rays

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

• Predict how current will change when resistance of the circuit is fixed and voltage is varied.

Online problems where the student is required to simplify the expression using the product property of exponents.

An activity explaining the properties of exponents.

Electrical devices convert the electrical energy carried by the charges into other types of energy such as heat, sound, and motion. Components in the appliance resist the flow of charge and are referred to as resistors. In this unit1 you will understand what resistance is, the factors that affect the resistance and the relationship between resistance and current.
