Electricity

Current is...

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

Voltage is simply defined as...

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

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

current is measured in....

• volts
• amps
• watts
• mph

What is resistance measured in?

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

A circuit with only one path for the current to flow is a __________________.

• parallel circuit
• series circuit
• mini circuit
• device

A complete, unbroken path that charges can flow through is called an __________________.

• conductor

• electric circuit

• electric current

• insulator

What is the resistance of a light bulb that has 3 A flow through when it is placed across 9 V?

• 1/3 ohms

• 3 ohms

• 27 ohms

• 9 ohms
