| Key Ideas |
| 1. There are two types of electric charges: positive and negative charges.
2. Like charges repel, unlike charges attract. 3. Electric charge is measured in coulombs (C). 4. Electrostatic charging of insulators by friction involves a transfer of electrons. 5. Electrical insulators do not conduct electricity because they do not contain mobile charged particles. 6. Electrical conductors are able to conduct electricity because they contain mobile charged particles (electrons). 7. Electrical conductors can be charged by induction. 8. Electrical insulators that are charged can be neutralised (discharged) by heating or exposure to humid conditions. Electrical conductors that are charged can be neutralised by earthing. 9. During electrostatic charging and discharging, only electrons are transferred. 10. An electric field is a region in which an electric charge experiences an electric force. 11. The direction of the electric field is the direction of the force acting on a small positive charge placed in the field. 12. Some hazards of electrostatic charging are lightning, and electrostatic discharge near flammable substances. 13. Electrostatic charging is used in photocopiers, electrostatic precipitators to reduce air pollution, spray painting to produce an even coat of paint. |
IMPORTANT STUDY POINTS
| 1. | Be aware of the formula Q = nq to calculate the number (n) of charge carriers given the the charge (q) on one particle and the total amount of charge (Q). |
| 2. | As 1 C is a large amount of charge, must know how to use or convert units such as millicoulomb and microcoulomb. |
| 3. | Must know the difference between how insulators and conductors are charged, and how they are discharged, and be able to explain these processes only in terms of the transfer of electrons. |
| 4. | Must know the difference between what happens when an insulator touches a charged object and when a conductor touches a charged object. |
| 5. | Must know the correct sequence for producing two similarly charged conductors, two oppositely charged conductors and a single charged conductor. |
| 6. | Must be able to define electric field and draw electric field patterns. |
| 7. | Be able to describe the dangers of electrostatic charging. |
| 8. | Be able to describe how electrostatic charging is used in photocopiers, precipitators and spray painting. |
Hope the above helps.

J2 H1 ECONOMICS HEAD START
Get a Head-Start in your J2 H1 Economics before the school term begins! Our Head-Start courses are planned and solely taught by MOE trained teachers with experience teaching in JC and running their own tuition centres, with their own unique set of notes, lecture materials, and coursework.
Each course comes with its own diagnostics to help you to identify the root cause of your issues, be it inadequacies in content, unable to tackle the question fully or always not using the right words for the answers. Your work will also be fully assessed, and a full review will be done with you by the end of the class.
Students will also be exposed to 2 to 3 case studies and several essays across various topics with quality and assessed answers written by students. We believe it is more authentic rather than the school’s suggested answers since it was all done under timed conditions. After covering the fundaments learn in J1, we will also be touching on a few key topics in J2. This is especially useful for those who will be missing out first few months of studies in school due to orientation commitments or inter-school competitions.
It will be content intensive and include the following:-
– 1 hour content delivery and application,
– 30 mins of application and
– 30 mins of understanding examiners through live marking and examiners’ reports.
Choose any of the 3 days available on Wednesdays:- 29 Nov or 6 Dec or 27 Dec
Choose any of the topics you require:-
10 to 12 noon – Central Economics and Price Determination
1230 to 230pm – market failure
