1. Subject Description: Electricity and magnetism Lab
This laboratory is to introduce the basic practical skills necessary for electricity and magnetism curriculum. This is done by directly training the students in creating and analyzing of real circuits. Experiments that can be conducted on the circuit theory include DC circuit analysis. This course, Electricity and Magnetism Lab, is one of the main components of an introductory calculus-based physics. Topics include Capacitance, Current and Resistance circuits.
2. Require Background or Experience
Experiments, are designed parallel to the theoretical concepts which are introduced to the students in the lectures
3. Subject Objective
A. Knowledge and understanding:
Students will understand the difference between AC and DC electricity and the basic concepts of technical physics with a focus on practical experiments.
B. Subject-specific and practical skills:
This is done directly by training the students in creating and analyzing of real circuits, current, voltage and electrical resistance measurements. Also the student learn how to prepare reports that give specific information about a test, experiment or research project that were completed in a lab. Generally, lab reports are scientific in nature and include many pieces of information, like the materials and methods which are used, results and discussions.

Sample of question and answer:
Consider a wire which has a circle cross section with diameter 8mm and length of 2m. The resistance measurement of wire is 3.82m?. Calculate specific resistance of this wire? By using below table determine type of wire? And also calculate percent of error?
IronCopperGoldSilver9.68×?10?^(-8) (?.m)1.69×?10?^(-8) (?.m)2.35×?10?^(-8) (?.m)1.62×?10?^(-8) (?.m)
Answer
Iron
Percent error=|9.68-9.59584|/9.68*100=0.869
In the below circuit the capacitor is full. We connect switch of S to b, prove the charge of capacitor that will determine by q=q_0 e^(-t/RC) during discharge? If q0=4C, R=4k? and C=2200?f Find the amount of charge and current circuit after 10s?
