Voltage is simply defined as...

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

What is voltage?

• The flow of protons

• The number of charged particles that pass each second
• The difference in potential energy of charged particles
• The rate at which energy is being transformed

What is resistance measured in?

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

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
