## Lesson 1 – Question 1

Sorry, but that is incorrect. You might want to go back and look at the picture of the atom and try again.

## Lesson 1 – Question 1

Sorry, but that is incorrect. Please try again.

## Lesson 1 – Question 1

Good job! The nucleus of an atom contains neutrons and protons.

## Lesson 1 – Question 2

Good Job! The neutrons have a neutral charge.

## Lesson 1 – Question 2

Sorry, but that is incorrect. Please try again.

## Lesson 1 – Question 2

Sorry, Please try again.

## Lesson 1 – Question 3

Sorry, Please try again.

## Lesson 1 – Question 3

Good Job! 120 Volts

## Lesson 1 – Question 3

Sorry, Please try again.

## Lesson 2 – Question 1

Sorry, but that is incorrect. In some things, it may even cause some damage. Please try again.

## Lesson 2 – Question 1

Good job!

## Lesson 2 – Question 2

Good Job! Regular household current is Alternating Current.

## Lesson 2 – Question 2

Sorry, but that is incorrect. Please try again.

## Lesson 2 – Question 2

Sorry, Please try again.

## Lesson 2 – Question 3

Sorry, incorrect. In the USA, we have 60 Hertz, or 60 Cycle. But in one cycle, the curent goes first one way, and then the other, 60 times in one second. Please try again.

## Lesson 2 – Question 3

Good Job! In the USA, household current reverses direction twice per cycle and we use 60 cycles per second, or 60 Hertz.

## Lesson 2 – Question 3

Sorry, you are thinking of Direct Current. Please try again.

## Lesson 3 – Question 1

Sorry, but that is incorrect. When the circuit is complete, current can flow.

## Lesson 3 – Question 1

Sorry, but that is incorrect. Please try again.

## Lesson 3 – Question 1

Good job! When the circuit is complete, current can flow.

## Lesson 3 – Question 2

Good Job! A resistor in a circuit reduces the amount of current.

## Lesson 3 – Question 2

Sorry, but that is incorrect. Please try again.

## Lesson 3 – Question 2

Sorry, Please try again.

## Lesson 3 – Question 3

Sorry, You might want to look at question 2 and then try again.

## Lesson 3 – Question 3

Good Job! When we added the resistor to our circuit, the current would be reduced and the light bulb would get dimmer.

## Lesson 3 – Question 3

Sorry, Please try again.

## Lesson 4 – Question 1

Sorry, but that is incorrect. In the next lesson, resistors in parallel, that answer would be correct.

## Lesson 4 – Question 1

Sorry, but that is incorrect. Please try again.

## Lesson 4 – Question 1

Good job! For resistors in series, you add them up.

## Lesson 4 – Question 2

Good Job! I=V/R

## Lesson 4 – Question 2

Sorry, but that is incorrect. Remember the triangle, I=V/R. Please try again.

## Lesson 4 – Question 2

Sorry, but that is incorrect. Remember the triangle, I=V/R. Please try again.

## Lesson 4 – Question 3

Sorry, but that is incorrect. Remember the triangle, V=I times R. Please try again.

## Lesson 4 – Question 3

Good Job! V=I times R

## Lesson 4 – Question 3

Sorry, but that is incorrect. Remember the triangle, V=I times R. Please try again.

## Lesson 5 – Question 1

Sorry, but that is incorrect.

## Lesson 5 – Question 1

Sorry, but that is incorrect. Please try again.

## Lesson 5 – Question 1

Good job! Since the two resistors are the same value, the current will be the same thru each one.

## Lesson 5 – Question 2

Good Job! Since they are in **parallel**, it is like two table lamps. If one burns out, the other lamp stays lit.

## Lesson 5 – Question 2

Sorry, but that is incorrect. They are separate independent circuits.

## Lesson 5 – Question 2

Sorry, That would be true if they were in **series**. Please try again.

## Lesson 5 – Question 3

Sorry, Since they are both wired directly across the battery, they each will have the full battery voltage across them. Please try again.

## Lesson 5 – Question 3

Good Job! They each will have the battery voltage across them, 10 volts.

## Lesson 5 – Question 3

Sorry, The values wouldn’t matter since each resistor is wired directly across the battery. Please try again.
