Electricity Basics

The voltage level received at a typical residence is

• 12 volts
• 60 volts
• 120 volts
• 240 volts

Wrapping an energized conductor around an iron bar creates an

• transformer
• inductor
• electromagnet
• permanent magnet

Tag out requirement requirements are set forth by

• EPA (Environmental Protection Agency)
• OSHA (Occupational Safety and Health Administration)
• NIOSH (National Institute for Occupational Safety and Health)
• ANSI (American National Standards Institute)

Which of the following values can be measured by placing a meter in series with an energized load

• Current
• Power
• Resistance
• Voltage

Which of these values must measured with power off

• Voltage
• Current
• Frequency
• Resistance

A short Circuit is what happens when

• a correct path for electrical current that follows the normal circuit.
• an unintended path for electrical current that bypasses the normal circuit.
• a device that regulates electrical flow in a circuit.
• a type of electrical component used to enhance circuit performance.

The path that electricity takes is called the

• voltage
• battery
• wire
• circuit

If the electricity leaves it’s intended path it’s called a

• overload condition
• ground fault
• open circuit
• short circuit

What is the unit for resistance

• Joule
• Volt
• Ohm
• Watt

What is the unit for voltage
