When a bulb goes out in a parallel circuit, what happens to the rest of them?

They will all still work

200

If I told you that R2=8A, what is it measuring?

Current

300
Do you think Christmas Lights are an example of a series circuit or a parallel circuit? why do you think that?
They are an example of a series circuit because if one of the bulbs burns out the entire strand will not light up.
300

How do you solve for total current in a series circuit?

They are all the same 

400

Solve for the total resistance in a parallel circuit with the following values:

R1=12Ω

R2=6Ω

R3=10Ω

R Total = 2.86Ω

To be determined by Ms. P
400

If a bulb goes out on a series circuit, why do the rest of them go out as well?

Because there is only one pathway for the current 

500

Solve for total resistance in a parallel circuit:

R1 = 2Ω

R2 = 4Ω

R3 = 3Ω

R4 = 6Ω

R5 = 4Ω

R6 = 5Ω

R Total = .59Ω

500

In order to find the voltage (with a formula) what two variables do you need? 

Current & Resistance

OR

Current & Power

500

If all the loads of a robot were wired in a series circuit, what would happen if the one of the lightbulb's in the robot burned out?

All the loads of the robot would not work because the electricity only has one path to follow in a series circuit.

500

What is the definition of electricity?

The flow of electric current
