Unit 5

• Ohm's law
• Newton's law
• Faraday's law
• Einstein's equation

A path that only allows for one route for an electric current is called a

• parallel circuit
• parallel current
• series circuit
• series current

Electric charge that has accumulated on an object is referred to as

• static electricity
• current electricity
• current circuit
• circuit electricity

A circuit that has two or more branches for electrons  to follow is a(n)

• series circuit
• electron circuit
• circuit diagram
• parallel circuit

The rate at which an electrical device converts energy from one form to another is called

• electrical energy
• electrical power
• electrical resistance
• voltage regulation

A static discharge differs from an electric current is that a static discharge

• involves the movement of ions as well as electrons
• is a flow of electrons
• lasts for only a fraction of a second
• results because a force is exerted on the electrons

A material through which electrons do NOT easily flow is a(n)

• conductor
• fuse
• insulator
• transformer

Lightning is

• a buildup of neutrons
• harmless
• a high-voltage electric current
• a large discharge of static electricity

Which of the following is a device designed to open an overloaded circuit and prevent overheating?

• circuit breaker
• magnet
• resistor
• transformer

Current that does NOT reverse direction is called

• direct current
• magnetic current
• alternating current
• circuit current
