4. What can you relate amperage to in nature?

5. What is coulomb and how is it used? Make sure to give an example of it being used.

6. Why are coulombs negative?

7. How does a coulomb relate to a ampere?

8. Define Voltage and give an example in real life.

9. What is the equation for power? What is its units? How does that relate to a light bulb?

10. Use the equation above to solve this problem: How much power is a light bulb producing if it is using .5 amps at 120 volts?

11. There are two types of electrical current AC and DC. Fill out the table describing each.

Answer 1

A common unit of electric current is the ampere, which is defined as a flow of one coulomb of charge per second, or 6.2 × 1018 electrons per second.
