Electricity Test 1 Review

Static electricity is:

• electricity flowing in a wire
• the buildup of electric charges on an object
• when protons move between objects

Two objects with LIKE static charges will

• attract each other
• even out in the end
• repel each other
• cause a spark

Which is an example of static dischage?

• a motor
• lightning
• thunder
• insulators

Static charges build up when

• protons move within an object
• electrons move within an object
• neutrons move within an object
• the nucleus moves within an object

Is it possible to CREATE electrons?

• Yes, that's what static electricity is.

• No, you can move them, but they are never created or destroyed.

• Sometimes, it depends on the voltage.

• Sometimes, it depends on the element.

If two objects with static charge are attracted, what do you know about them?

• They are both positively charged.
• They are both negatively charged.
• One is positively charged and one is negatively charged, but you won't be able to tell which is which.
• One is positively charged and one is negatively charged, and you can tell which is which by looking at them.
