Ch. 6 Sec. 3 Flashcards
What happens to the voltage in a parallel circuit?
The same voltage is provided across each resistor
What happens if one bulb is not in motion or removed?
The circuit path to the other bulbs is not effected
If one bulb is out of commission, does the light still work?
Yes. The bulb is lit up
What is electric charge?
A fundamental property of matter
Can the charge be negative or positive?
Yes
What is a proton?
A positive charge particle
What is the charge of a proton?
1.7x10^-19
What is the mass of a proton?
1.7x10^-27
What is an electron?
A negatively charged particle
What is the charge of an electron?
-1.6x10^-19
What is the mass of an electron?
9.1x10^-3 kg
What is an ohm?
The SI unit of electrical resistance
What is the symbol for ohm?
The Greek symbol omega
What does k=?
Number of resistors
What does I stand for?
Current
What does R stand for?
Resistance
What does V stand for?
Voltage
Do electrons move in electric circuits?
Yes
Like charges repel…?
Opposite charges attract
What did scientists agree upon?
A standard package of electric charge called a coulomb
Batteries of generators provide what?
Energy to the electrons
Do protons flow?
No they do not because they are locked with atoms
What do electrons carry?
The electric current as they flow through the circuit path.
What do electrons deliver?
Energy that is transformed into light and heat by the light bulb.
What is a parallel circuit?
A circuit that provides separate paths for current to travel through each resistor
