### Re: The Resistor [Post Homework Here]

What is electrical resistance?

its an electrical unite describe the voltage that has to be applied to pass unity of current from point to another.

 What ‘Units’ are used to describe electrical resistance?

OHM'S

Convert the value of 100,000Ω into Kilo-Ohm and Milliohm.
100,000 equals 100 kohm and equals 100,000,000 Milliohm

 Which would work better to connect a circuit together: Silver or Plastic? Why?

silver,its a sort of metal that has a conductivity and its resistance for current is low,but plastic has very large resistance
prevents any current to flow.

I hope you were able to perform the insulators vs. conductors experiment. That is a very fundamental idea about resistors and electricity!

HOMEWORK QUESTION 1
What is electrical resistance?
Resistors act like a funnel in an electrical circuit dropping the amps through resistance.

HOMEWORK QUESTION 2
What ‘Units’ are used to describe electrical resistance?
The Ohm (greek symbol omega) is the units of measure of resistance.

HOMEWORK QUESTION 3
Convert the value of 100,000Ω into Kilo-Ohm and Milliohm.
100 Kilo-Ohm = 100,000,000 Milliohm

HOMEWORK QUESTION 4
Which would work better to connect a circuit together: Silver or Plastic? Why?
Silver, as plastic has a higher resistance than silver

What is electrical resistance?
its a measure of how strongly a material oppose current to flow.

What ‘Units’ are used to describe electrical resistance?
OHM

Convert the value of 100,000Ω into Kilo-Ohm and Milliohm.
100,000Ohm-100KOhm and 100,000Ohm-100,000,000 mOhm

Which would work better to connect a circuit together: Silver or Plastic? Why?
Silver, because it have low electrical resistence.

Hi Shawn, Karin,

All your answers are right, good work! I hope you followed the experiments in the video as well. One additional experiment you can do is turn your Digital Multi-Meter (DMM) to the Ω setting and check the different resistances of materials, metals, plastics, glass, clothes, play-dough, water, your hand..etc...

HOMEWORK QUESTION 1
What is electrical resistance?
It´s a force of opposition to the flow of electrons that a material posseses
HOMEWORK QUESTION 2
What ‘Units’ are used to describe electrical resistance?
The unit is Ohms(Ω)
HOMEWORK QUESTION 3
Convert the value of 100,000Ω into Kilo-Ohm and Milliohm.
100 kΩ and 100,000,000 Milliohms
HOMEWORK QUESTION 4
Which would work better to connect a circuit together: Silver or Plastic? Why?
