If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

• friction destroyed electrons in the rod.

• the silk has become negatively charged.

• protons have moved to the rod.

• glass attracts more protons.

Answer explanation

Which one is a series circuit?

• 
• 
• 
• 

Answer explanation

All of the other examples are a simple circuit. This ones is a series circuit because it has two loads(items) that used electricity.
