As the resistance of a circuit increases (voltage remains constant), the current will

• increase

• decrease

• stay the same

The difference in electrical potential energy between two places is called

• resistance
• friction
• induction
• voltage

If the current through a circuit is 2 A and the resistance of a light bulb in the circuit is 10 Ohms, what is the voltage difference across the light bulb?

• 5 V
• 12 V
• 0.2 V
• 20 V

What is electric current?

• The number of charged particles that pass a point each second
• The difference in potential
• The resistance
• Light Emitting Diode

If both sides of a light bulb are at the same voltage, what happens to the light bulb?

• It glows very brightly
• There is no light
• The brightness of the light will vary over time
• The bulb will explode

What 'flows' in a wire?

• Protons
• Neutrons
• Atoms
• Electrons
