Unit 13 Review Electricity

Grounding is when excess electrons (or charge):

• Builds up on and object, making an object negatively charged

• Builds up on and object, making an object positively charged

• Is released into the ground, making the object neutrally charged

• When a neutrino is sent to his room by his neutron.

When giving an object a static charge by friction (like rubbing a balloon on your hair). Only _______ transfer from one object to the other.

• electrons

• neutrons

• protons

• none of these
