Metals such as copper and aluminum are good ______________. 

• insulators
• conductors
• circuits
• charges

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

Electric Current is...

• The flow of charge

• The flow of volts in a given time

• The flow of charge in a given time

• The rate of flow

Calculate current if a charge of 10 Coulombs flows past a point in 5 seconds

• 2 Amps

• 50 Amps

• 0.5 Amps

Calculate the charge that passes a point in 20 seconds if 500mA flows for this time.

• 10 000 Coulombs

• 25 Coulombs

• 10 Coulombs

• 0.025 Coulombs

The correct symbol equation is:

• Q = I / t

• I = Q x t

• t = I / Q

• Q = I x t

To measure current we use

• an ampmeter

• a voltmeter

• a geiger counter

• an ammeter

What is an electrical circuit?

• a whole bunch of wires

• a broken path that electric charges can flow

• a circuit board

• a complete, unbroken path through which electric charges flow

When a switch is open...

• the circuit is working and gives energy

• the circuit is broken and charges cannot flow

• the circuit is turning lights on
