The correct answer is:
A
Static electricity involves a negative charge that is not moving, and current electricity involves a negative charge that flows.
Electricity is the energy made by electrons. Electrons have a negative charge. They orbit around the outside of atoms. When electrons builds up on an object, that object becomes negatively charged. When that charge is stationary, or static, we call it static electricity. Static electricity is the reason you sometimes get a shock when you touch a doorknob. It’s also the reason for lightning. When electrons flow in a closed loop, they produce electrical energy, too. Unlike static electricity, that energy is moving. The water that flows in a river is called a current. The energy of moving electrons is also called a current. Current electricity is electricity that flows through an unbroken path.
Based on the passage, what is the difference between static and current electricity?
A
Static electricity involves a negative charge that is not moving, and current electricity involves a negative charge that flows.
B
Static electricity produces lightning, while current electricity produces heavy rain.
C
Static electricity is made by electrons, and current electricity is not.
D
Static electricity is a type of energy, and current electricity is not.
