1 What we will do What we will learn 12Px 04 Hongongoi 2017
Preliminaries and roll How to start well Introduce the rheostat and explore its use as: Variable resistor Potentiometer or Voltage Divider See how a 12V radio can be installed in a 24V truck without frying Potentiometer or Voltage Divider: what it is and how it is used in the auto industry & electronics Mark the HW that is due today How to stay on track for 10 Nov (129 days from now) Use Mr H’s website to access practice questions (to lift our marks) How to push our grades up. (Pushing is never easy)

5 Homework Marking No. of marks What for 1
Having sketches & FULL working for all Neat presentation and down-page format Answer underlined and units given Self marked and all correct – eventually In on time and signed for (“This is my own work”…….) Total A mark out of five that will contribute to the “homework” grade in the reports

6 Example: One trillion electrons are put onto a plastic ball. The ball is put into an electric field that has a strength of 200 Newtons per Coulomb (N/C). What is the force on the plastic ball? E=F/q F=E.q F=
