8. Correct! Great job! Current is the movement of electrical charge within a conductor! Proceed to Next Question! This movement of electrical charge is from the movement of free electrons traveling from atom to atom!

9. Sorry, but this is a wrong answer! Current is the movement of electrical charge within a conductor! Return to Question!

10. Correct! Great job! Voltage is a measurement of electrical force, sometimes referred to as EMF or “potential”. Proceed to Next Question! Voltage is sometimes compared to water pressure. I think it is best understood as a difference-in-potential or a measure of amplitude! The amplitude on the above sine wave would be 400 volts!

11. Sorry, but this is a wrong answer! Voltage is a measurement of electrical force, sometimes referred to as EMF or “potential”. Return to Question!

12. Correct! Great job! Wattage is a unit of measurement for Power. It is based on the rate of electrical energy transferred in a circuit! Proceed to Next Question! What is the Power in units of Watts, if V=12vdc and current I=3 amps ? Using the equation wheel for power: P = V x I

13. Sorry, but this is a wrong answer! Wattage is a unit of measurement for Power. It is based on the rate of electrical energy transferred in a circuit! Return to Question!

14. Correct! Great job! A Circuit is a complete path for the flow of electrical current! Proceed to Next Question! An open circuit allows NO current flow! Remember that it can still be energized with measureable voltage! More complex – but still a circuit!

15. Sorry, but this is a wrong answer! A Circuit is a complete path for the flow of electrical current! Return to Question!

16. Correct! Great job! Resistance is the term used to represent the forces that oppose electrical current flow in a circuit or conductor! It is measured in OHM’s. Proceed to Next Question! This resistance is measured in OHM’s (symbol “R”) and when considered in a circuit with Voltage (symbol “E”) and Amperage (symbol “I” representing current), the mathematical relationship can be expressed: E = IR This is called OHM’s Law!

17. Sorry, but this is a wrong answer! Resistance is the term used to represent the forces that oppose electrical current flow in a circuit or conductor! It is measured in OHM’s. Return to Question!
