Upon completion of Basics of Electricity you will be able to:

•  Explain the difference between conductors and insulators
•  Use Ohm’s law to calculate current, voltage, and resistance
•  Calculate equivalent resistance for series, parallel, or series-parallel circuits
•  Calculate voltage drop across a resistor
•  Calculate power given other basic values
•  Identify factors that determine the strength and polarity of a current-carrying coil’s magnetic field
•  Determine peak, instantaneous, and effective values of an AC sine wave
•  Identify factors that effect inductive reactance and capacitive reactance in an AC circuit
•  Calculate total impedance of an AC circuit
•  Explain the difference between real power and apparent power in an AC circuit
•  Calculate primary and secondary voltages of single-phase and three-phase transformers
•  Calculate the required apparent power for a transformer

This knowledge will help you better understand customer applications  In addition, you will be better able to describe products to customers and determine important differences between products.
