Voltage, Current and Resistance

What is the current in an electric circuit?

• The energy of the circuit

• The flow of electrons in the circuit

• The power of the circuit

As the resistance of a circuit increases, the current will

• increase
• decrease
• stay the same

What 'flows' in a wire?

• Protons
• Neutrons
• Atoms
• Electrons

______________ do not allow electricity to flow through easily.

• Conductors

• most metals

• insulators

Why do conductors allow electricity to flow but not insulators?

• Conductors are magnetic and allow electromagnetism.

• Conductors have channels that electrons can flow through

• Conductors have loose electrons.

• Insulators have small breaks in them that block electric current.

What do electrons hate more than anything?

• Being around other electrons

• Protons

• Neutrons

• Questions that imply that electrons have feelings

When is a battery truly dead?

• When all the electrons on one side make it to the other side

• When there are the same number of electrons on both sides.

• When somebody licks it and then there's nothing to live for. So humiliating.

• When it's really cold
