Electric Current

Which word means how hard it is for electrons to flow?

• Current
• Voltage
• Resistance
• Power

This is an example of a _______ circuit

• open
• series
• parallel
• square

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

What characteristics impact resistance of a material?

• Thickness 
• Temperature
• Length
• All of these

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

A light bulb is an example of a _______.

• current
• resistor
• battery

An object through which electrons can easily flow is called a(n) ___________.

• Conductor
• Insulator
