Question 2 • Physical Science

Why does Chelsea see sparks as she removes her clothes from the clothes dryer?

Answer
A
static discharge
B
loss of protons
C
conduction
D
induction

Explanation

Friction between the clothes as they tumble in the dryer transfers electrons, leaving some items with an electric charge. When Chelsea removes them, charge can suddenly jump through the air between the clothes or to her, producing tiny sparks. This is a static discharge, not conduction or induction.
