Electric Current

An electrical conductor is best defined as a:

• Material containing free-flowing electrons
• Material that slows down the flow of free electrons
• Material that stops the flow of free electrons
• Material that contains free-flowing protons

An electrical insulator is best defined as a:

• Material that slow down the free flow of electrons
• Material that increases the free flow of electrons
• Material containing free-flowing electron
• Material that contains free-flowing protons

A property of certain materials that impedes the flow of electricity in a circuit is called:

• Resistance
• Power
• Current
• Voltage
