|
|
Be able state Ohm's law in words and mathematically. |
|
|
Be able to define the units Ampere, Volt, Ohm etc. |
|
|
. Key Terms and concepts: Emf, internal resistance, resistor, terminal voltage, Kirchhoff's junction and loop rule, Wheatstone Bridge, Potentiometer, RC circuit, Applications of RC circuits |
|
|
Be able to calculate the equivalent resistance for resistors in series, parallel, and combination. |
|
|
Be able setup a set of simultaneous equations for a circuit that has loops with Emfs and resistors as well junctions with incoming and outgoing currents. If you have a graphic calculator form HP, TI, Casio etc.. read the section on Matrices, Simultaneous equation Solver, etc. in you calculator manual and then be able to reproduce the results in example It is very important that you master how to solve simultaneous equations using you calculator. |
|
|
Basically the equation is AX = B when A is a Matrix of N X N square matrix, X are you N unknowns, B is the RHS of the equation. |
|
|
The solution is X = A(inverse)* B . i.e X =B/A. Visit the following link to learn how to use your TI 83 to solve simultaneous equations. http://www.ecs.umass.edu/~chang/TI83.htm |
|
|
Be able to use your calculator's capability to solve simultaneous equations. |
|
|
Be familiar with RC circuits and some of their important applications. |
|
|
Be able to calculate the resistance needed to convert a galvanometer to an ammeter as well as a voltmeter. |
