This course covers the Basics of Electrical Theory and is  designed to prepare you for subsequent courses  provided by Siemens.

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 kVA of a transformer
