I charge a balloon with negative charge by rubbing it to my hair and when I put it close to another neutral object it attracts to it.
This is an example of whart type of electrons transfer?
We can observe 2 examples:
By contact when you rub the balloon to your hair and by induction when the balloon induce attraction to another neutral object.
Name the electrical conductos components of a power cord
The internal wires and the power cords are normally metallic
What does Ohm's law state?
Ohm's law states that the current through a conductor is directly proportional to the voltage.
What's the country with the largest population?
China
What's the smallest subatomic particle of the atom?
The Electron
Your phone is running out of battery, you plug it in and starts charging its battery.
This is an example of what type of electrons transfer?
By induction
In what units is measured the resistance of a circuit and with what symbol is represented?
The resistance is measured in Ohms symbolized by the Greek letter omega (Ω )
Calculate the voltage in a circuit if the resistance is equal to 50Ω and the current is 200A.
V= IR
V= (50Ω )(200A)=10,000 V
What was the first metal used by humans?
Copper
Particle that carries electricity
Electron
Can you produce an static discharge if you rub your hand to a sweater and then touch a metallic object? Explain
Yes, since you are polarizing your hand by concentrating the electrons on it and then if you touch an object you will transfer those electros and cause a discharge, still, this won't happen all the time.
What's the difference between an electric current and electric circuit?
Electric current is the charge that flows through the circuit. Electric circuit is the path of conduction wires through which current flows.
Calculate the current in a circuit if the resistance is equal to 0.5Ω and the voltage is 16V.
I=V/R
I=(16V)/0.5Ω )=32A
In what country is located the University of Crambidge?
In the United Kigndom
