Current is...

• moving protons
• moving electrons
• measured in volts
• measured in ohms

current is measured in....

• volts
• amps
• watts
• mph

The two types of current are...

• AC/DC
• Alternating Current
• Direct Current
• All of the above

Voltage is simply defined as...

• what 'pushes' electrons
• what 'stops' electrons
• moving electrons

In the U.S most electrical outlets supply a voltage of....

• 240 Volts
• 120 Volts
• 100 watts
• 60 amps

Resistance is...

• What "slows down" electrons
• What "speeds up" electrons
• Moving electrons
• What "pushes" electrons

If the voltage stays the same, but the resistance goes up, the current will....

• increase (speed up)
• decrease (slow down)
• stay the same

If the current increases it could be because of...

• increasing voltage
• decreasing resistance
• both

Electrical current will pass easily through metals such as copper, aluminum and gold. These metals are good

• things

• insulators

• charged particles

• conductors
