SACE Stage 2 Physics Electric Fields 1 Solution 1. (a) State Coulomb’s Law. Any two point charges have acting on them equal sized oppositely directed forces acting along the line joining their centres. The magnitude of these equal sized forces is directly proportional to the product of the charges and inversely proportional to the square of their distance apart. The forces are attractive for unlike charges and repulsive for like charges. [pic]. e.g.

to let people know when to enter and also to research and learn more about parallel and series circuits. Introduction I am going to design an electric circuit for a Doctor’s surgery. There are two types of circuit’s Parallel circuit‚ and Series circuit. First I am going to explain what a circuit is and what the differences they have are. An electric current is a flow of charge. The charges are given energy and made of flow using a cell or a battery. Charges can flow easily through connecting

6. To make the circuit “cold”‚ what do you need to do? WHY? Turn the resistance up and the voltage down. It completely stops the flow of electrons through the battery. Which means the battery is not able to work because there is no electric current being created. 7. Describe the relationship between voltage and
