What Is Electricity?

1. Electricity is the flow of ______

2. Electrons have a ______charge.

3. Protons have a ______charge.

4. Neutrons are ______.

5. When electrons move among the atoms of matter, a ______of ______is created.

Resistance, Conductors, and Insulators

6. Resistance in wire depends on

a.

b.

c.

7. is used in many wires because it has a lower resistance than many other metals.

8. What are insulators?

9. Name 2 insulators:

10. What is static electricity and how is it different from current electricity?

11. Who first coined the terms “positive” and “negative” when describing electricity?

How Is Electricity Measured?

12. The pressure that pushes electrons in a circuit is called .

13.Voltage is a measure of the pressure, or electromotive force applied to make electrons .

14. is defined as electrons flowing between two points having a difference in voltage potential.

15.Current is measured in or (A).

16.One ampere is electrons per second passing through a circuit.

17. is a property that slows the flow of electrons—the current.

18. George Ohm, a German physicist, made an important discovery about electricity in the early 19th century. He foundthat in many materials, especially metals, the that flows through a material is proportional to the across the material.

19.Ohms Law can be written as Voltage (Volts) = (Amps) x(ohms).

20.Electrical power is the atwhich electricity is or .

21.The electrical power formula is Power = x
