## Entertainment Electrics on DVD: Foundations of Electricity, Power Distribution, and Control Systems

Entertainment Electrics on DVD is a series of videos on DVD presented by ETCP Recognized Trainer Richard Cadena. Each video is about 10 to 15 minutes long and covers a single topic related to live event production electrics. Each is followed by a short quiz to test your knowledge and retention.

Part 1 covers DC electricity, terminology, basic circuits, Ohm's law, DC power, AC electricity, impedance, AC power, phase angles, power factor, 3-phase power, harmonics, and more.

This course covers topics that are listed as being in the content outline for the ETCP Entertainment Electrician Certification Exam. Additional resources are also offered, such as video, reading material, and web pages.

Part 1 covers the first day of class and Parts 2 and 3 are available at an additional cost.

## Useful Formulas

Ohm’s Law:

V = I x R

I = V ÷ R

R = V ÷ I

###### Single-Phase AC Power:

P (watts) = V (volts) x I (amps) x Power Factor

###### Three-Phase AC Power:

P3∅ (watts) = V (volts) x I (amps) x Power Factor x 1.732

###### Power Factor:

PF = cosine (phase angle)

PF = Power (watts) ÷ [ V (volts) x I (amps)]

PF = Real Power (watts) ÷ Apparent Power (VA)

Apparent Power:

Apparent Power (VA) = V (volts) x I (amps)

Peak Voltage:

Vpeak = Vrms x 1.414

RMS Voltage:

Vrms = Vpeak x 0.7071

Inductive Reactance:

XL (ohms) = 2 x π x ƒ x L

where XL is the inductive reactance, π is pi (3.14), ƒ is the frequency in hertz, and L is the inductance in henrys
