Title: Lesson
Course: Electrical Theory (IC 101-IC 101) > Section: Web Content

This weeks encompasses a lot of material, be sure to give yourself some extra time this week.
Key elements of week 4:
Understanding charging and discharging of capacitors
Factors that effect capacitance
What happens to voltage and capacitance when capacitors are put in series and parallel
Capacitive reactance and how frequency is related
(ICE) Current leads Voltage in a capacitive circuit and the phase relationship between resistors and capacitors
Understanding charging and discharging of inductors
Factors that determine inductance
Series and parallel inductance and understanding mutual inductance
Voltage and current relationship in transformer and transformer core types and losses
Inductive reactance and frequency relationship
(ELI) Voltage leads Current in an inductive circuit and the phase relationship between resistors and inductors

Be sure to check out the videos below for explanation of material content.
There are one worksheet for you to complete under the "coursework" page.
This week the labs have increase to four, but each deals with the subjects of the week, such as Capactive Reactance, Inductive Reactance, Capacitor charge and discharge currents, and RL circuit phase shifts. These are very important elements to understand and will also help you in your final hands-on test.
This week there are five circuit challenges, four of the challenges are concerned with calculating phase angles and totals in RL and RC circuits. This should give you a thorough understanding of how AC circuits affect circuits. The other circuit challenge works on transformer characteristics.
