Electricity and Static Quiz

A student conducts an experiment to determine whether household objects are good conductors of electricity. She tests a wooden popsicle stick, a plastic straw, a gold ring, and a copper penny. Which of the following are most likely to be her outcomes? Choose two (2) correct answers.

• The wooden popsicle stick completes the circuit and the light bulb is lit.

• The plastic straw completes the circuit and the light bulb is lit.

• The gold ring completes the circuit and the light bulb is lit.

• The copper penny completes the circuit and the light bulb is lit.

Static electricity is generated when—
