Electronic electroscope

An electroscope is the instrument used to detect charged bodies. Here, an electronic version of the scope that is more sensitive as compared to its conventional counterpart and which helps indicate the polarity of charge has been described. This circuit consumes very low quiescent power and reliably indicates charge induction and detection. The polarity of […]

Electrolysis of copper (II) sulphate solution

This investigation will examine one of the factors that affect the amount off copper deposited during the electrolysis of copper (II) sulphate solution. Electrolysis is the decomposition of an ionic solution by electricity. The electricity splits ionic chemical compounds into separate components, for example, copper chloride can be split into Cu metal and Cl gas. […]

Electromagnetic Force

Electricity and magnetism are two different aspects of one force. This force is called the electromagnetic force. Electricity can be generated by rotating coils of wire in the vicinity of a magnet. When a force moves objects toward and away from each other it is called electricity. When it comes to magnets, Earth and other […]
