2018 Mod12 Flashcards
Write out the definitions for the following terms:
A. Photon
A small “package “of light that asked like a particle
B. Charging by conduction
Charging an object by allowing it to come into contact with an object that already has an electrical charge
Charging by induction
Charging in object without direct contact between the object and a charge
D. Electrical current
The amount of charge that travels past a fixed point in an electrical circuit each second
Conventional current
Current that flows from the positive side of the battery to the negative side. Even though it has been proven wrong
F. Resistance
The ability of a material to impede the flow of charge
G. Open circuit
Hey circuit that does not have a complete connection between the two sides of the power source.
Do negative and positive attract? What about negative and negative or positive and positive
Yes, no
The force between the south and pole of a magnet in the north pole of a Nother magnet is measured if the distance between two poles is increased by factor of three how does the new force compared to the old one? Is the force attractive or repulsive
It’s smaller ➗9
Attractive
Are you charged particles are placed 10 cm from each other and the resulting force is measured. They charge an object one is in doubled the in the charge on object to is left the same also the distance between the object is measured is reduced to 5 cm how does the new for us to get to the old force
Can you stronger by eight times
What causes the electromagnet force?
The exchange of photons
Giving your answer to question five why don’t charged particles glow?
Because the photons are too small to see
If you were to use a positively charged rod to charge an object by induction what charge with the object have
Negative
If you were to use a puzzle the fully charge ride to charge an object by conduction what would the charge of the object be
Positive
And electrical circuit uses a large voltage that small current is the energy of each electron high or low? Are there many electrons flowing to the Chris circuit or are there few? Is this circuit dangerous?
High, few, yes
Under what conditions is an electrical circuit reasonably safe?
Small current and small voltage
What is wrong with conventional current?
It assumes that the flow is a positive charges
If you have two wires. When his mom, and the other is short. Other than that, they are identical. Which has more resistance?
The long one
You have two wires. One is Dan, and the other is very sick. When the same current is run through each wire, which will get hotter?
The thin one
Three lights are in a circuit when one burned out, they all go out. When the burnt out what is replaced by a good light, the other two lights work again. Are the lights wired in a parallel circuit or a Siri circuit?
Series
If it takes a flow of charge particles to make a magnet, where is the charge particle flow in a permanent magnet?
Indian electrons in its Adams
Is it possible to have a permanent magnet was only a north pole?
No
Is it possible to make a magnet from something that’s not a magnet
Depends on the material but technically yes
If a material does not respond to a magnet what can you conclude about the Adams in that material?
They are on alignable
